U1-01: Archiving ARC System Enhancement Associates, Inc. $0-$50 #1576 is used to create and maintain file archives. It will also create self-extracting archive files. An OS/2 version is included. ----------------------------------- 7059/1862 LHA and Related Utilities Small Programs Disk ----------------------------------- LHA 2.13 Yoshizaki, Haruyasu $0 (formerly LHArc) is a file archiver that creates smaller archive files than anything else available. If this were not enough of an advantage, LHA is free, unlike ARC and PKZIP, which are shareware and require payment to the author for continued use. As most of you are aware, after getting an archived file, you normally have to have a de-archiver to extract the member files from it. As a result, the person distributing the file on disk, must sacrifice some of the space saved to make sure you have a compatible de-archiver. In the case of .ARC files, Vernon Buerg's small ARCE de-archiver minimized the problem, taking as little as 12k with its accompanying documentation file. Katz's PKZip package had the ability to create "self-extracting" archive files that didn't need a separate de-archiving program, but if you had several archives on one disk, the extra self-extracting code added to each archive could easily take up more space than, say, ARCE. On BBS's, if you already had ARCE, it made no sense to pay extra to download large self-extracting archives. But LHA's self-extracting code only adds a little over 1k to a file. LHScan and LHPick (LHSCAN) Yoshizaki, Haruyasu $0 saves uncorrupted files from a broken archive. LHScan scans for CRC errors. LHPick retrieves all files in LZH files free from CRC errors. 2LZH Bryeans, M. $0 is a small program that takes care of converting ZIP, ARC, or PAK files to LZH format (from LHarc). Just type 2LZH and it will convert all the files in the current directory. When it is done, it even tells you how much disk space you saved by converting to LHarc. BkLBat Goodell, Dan $0 automates the use of LHA to do back-ups. You can specify multiple lists of files to be backed up. ChkLharc 1.1 (CHKLARC) PAL Software $0 will search COM and EXE files to determine if they are self-extracting LHARC files, and, if they are, a determination is made whether the file contains an "AUTOLARC.BAT" file. (A self-extracting LHARC file has an automatic mode in which after extraction, it looks for a file named AUTOLARC.BAT and if present, runs it. Obviously, it would be easy for someone to put damaging commands in a batch file.) FV 1.37 Buerg, Vernon D. $0 will display the names and attributes of files contained within archive files. It will work with files with extensions of ARC, ZIP, PAK, DWC, LZH, ZOO, and most self-extracting .COM and .EXE files created by ARC, ZIP, and LZH. It will also work with the ZIP imploding method and PAK Distilling. You can also convert self-extracting archives and display ZIP file comments. LZComp $0 contains information, source code and history of the LARC, LZHUF, and LZARI programs. LHdel Hendricks, Duane $0 cleans up a directory by deleting any files in the current directory that are also in a specified LHarc file, including LHarc self-extracting files. If you have ever extracted files from an archive file into a crowded subdirectory, whether intentionally or accidentally, you know how much trouble it can be to delete just those files when you are through looking at them. Based upon the utility ARCdel for ARC files, this utility will clean out files from LHarc files and ZIPdel, also on this disk, will do the same for ZIP files. (The authors of ZIPdel are no longer at the address provided in the documentation.) LHdir 1.3 D & D Software Inc. $0 will let you see the contents of LHarc's self-extracting files; it will optionally convert the file back to an .LZH file; and it will scan all EXE and COM file in the current directory to see if any of them are LHarc self-extracting files. LH-HDR is a text file that gives the file layout of an .LZH file created by LHarc or compatible. LZHuf 1.0 $0 is the C source code for compression algorithm upon which LHarc is based. LHRead various authors $0 is for extracting and viewing the contents of LZH files created by LHarc. Unfortunately, it does not work with self-extracting LHarc files. It does, however, let you view text or PCX graphics files without unarchiving them to disk first. Mike's Archive Directory 2.0 (MAD) Sax, Mike $5 can show you the contents of every popular archive type available, including self-extracting files. New features include the ability to display only specified members of an archive, the display of the name and version of the program that created the archive, and the name, version and free space required to extract specified members of an archive. -------------------------------- END OF SMALL PROGRAMS DISK #1862 -------------------------------- ----------------------------------- 7059/2463 EXE Compression Utilities Small Programs Disk ----------------------------------- LZEXE 0.91 Bellard, Fabrice $0 compresses EXE files into a form from which they can still be run. This is like a self-extracting archive from which the program is extracted into memory and begins executing, instead of extracting onto disk as a new file. In our tests, the compressed file actually executed more quickly than the uncompressed file. The reason is that reading a large file from disk is often more time consuming than reading a smaller file and then decompressing it in memory. To give you an idea of the amount of compression it is capable of, the shareware file manager Qfiler compressed from 115.5k to 54.4k. We freed up megabytes on one 30meg hard disk by compressing just the EXE files that were 75k or greater. It will compress smaller EXE files, but the effect is less pronounced. It will compress COM files if you first convert them to EXE with the COM2EXE utility. The program even points out the presence of internal overlays, and indicates if the file has been packed with EXEPACK. As the author points out, if you are a programmer, you can compress your programs and impress everyone with what tight code you write. We sometimes get programs (mostly games) that have just the EXE file with the documentation built into the program, so there is no separate doc file. In the future, rather than archive such a file with LHarc, we will compress it with LZEXE. An LZEXE'ed file is actually smaller than a self-extracting LHarc'ed one. If a programmer has just an EXE and a DOC file, the EXE file could be compressed with LZEXE and the DOC file could be converted to a self-scrolling COM file with TXT2COM or ASC2COM, converted from COM to EXE, and compressed with LZEXE. With this combo, you get the space savings of archiving without the nuisance to the user of having to dearchive. This program comes from France. Since the only input to the program is giving the name of the file to be compressed on the DOS command line, the French progress reports are not important. The original documentation is in French, but an English translation of the documentation is provided. Also see LZEShell on Archiver Shells disk. Chk4comp 3.6 (CK4COMP) Land, John $0 shows which EXE & COM files have been compressed by any of a dozen different file compressors. Output is sortable by size or name and is redirectable. Subdirectories can also be processed. It can identify Windows programs, overlay files and misnamed EXE and COM files. ComToExe 1.0 (COM2EXE) Bellard, Fabrice $0 converts a COM file into an EXE file, primarily so that the file can then be compressed by LZEXE. Convert (CVT-LZ) Weeks, Gregory D. $0 translates the French strings in LZEXE.EXE, COMTOEXE.EXE, and UPACKEXE.EXE to English. This will only work on version .91 of LZEXE, ver. 1.01 of COMTOEXE, and version 1.00 of UPACKEXE. LZEShell 3.0 (LZESHEL) Petrakis, Peter $0 automates the use and interaction of LZEXE, COM2EXE, and EXEPAK. It gives prompts and messages in English when needed. It allows compressing COM files with one command, as it will automatically invoke COM2EXE first and then LZEXE. It also has the ability to run UNLZEXE, which compresses files that have been compressed by LZEXE. The program routinely checks the attributes of the file it's processing, and if it finds it is a read-only file it automatically changes it to read-write and proceeds from there. TinyProg 3.6 (TINYPRG) Tranzoa, Co. $39 converts EXE and COM programs to a smaller file size. The program will not work with internal overlays and programs that configure themselves by writing data back into the program file. It will not work with Windows/OS-2 EXE files. UnLZexe 0.5 Kou $0 uncompresses files that have been compressed by LZEXE. -------------------------------- END OF SMALL PROGRAMS DISK #2463 -------------------------------- -------------------------------------- 7059/4053 EXE Compression Utilities #2 Small Programs Disk -------------------------------------- CompFile (COMPFIL) Cohn, Dickford $0 is a text file comparing executable file compression programs, including Diet, PKLite, LZexe, and others. It also includes a theoretical discussion and tips for use of these programs. Diet 1.44 Matsumoto, Teddy $0 compresses executable files to save disk space, while still allowing them to be run. Wildcards are accepted, and retrieved original files have the same attributes and time stamp. EMS can be utilized. This is small and very fast, with minimal command line options. DirX 1.08 Kaya, Raymond T. $0 searches for executable files that have been compressed by LZEXE, PKLITE or AXE. In a two-column, scrollable display, it shows compressed files on the left and uncompressed ones on the right. DirXC 1.08 Kaya, Raymond T. $0 provides a simple means of showing which files have and have not been compressed with an executable file compressor. This is a smaller, command-line version of DirX, and the listing produced can be directed to a file or your printer. DISLite 1.15 JohnPC & CV-Tassle $0 expands programs compressed by PKLITE to their original size. LiteMenu 1.1 (LITEMNU) Borris Technologies $10 provides a menu system for PKLite. You can easily compress/expand files and specify a destination directory. Other features include on-line help, output overwrite options, the ability to make backup files, compression options regarding internal overlays, and more. PKLite 1.14 PKWare, Inc. ASP $46 lets you compress COM and EXE files to save disk space and run them without having to dearchive them to disk first. This is similar to LZEXE, but LZEXE does not work on COM files. Other advantages of PKLite include warning you if a program file uses overlays (such programs normally will not run if compressed), offering an Extra Compression mode and a decompressing option, support for DR. DOS 5.0, automatic header optimization, and more. Slim 1.10a Herity, Dominic ASP $45 is a 73k TSR and file that can greatly increase the effective space on your hard disk. You can compress files with it and it uncompresses them automatically when you access them. The 73k of RAM that it takes up is a significant drawback, but if you can spare the RAM, you will gain a LOT of disk space. NOTE: Slim is NOT an EXE file compressor. -------------------------------- END OF SMALL PROGRAMS DISK #4053 -------------------------------- PKZip, PKunzip, and PKsfx 2.04g PKWare Inc ASP $51 #7059/1705 is a popular utility for creating a ZIP (archive) file and for extracting files from a ZIP file. PKSFX lets you create a ZIP file that will self-extract. PKZipFix takes advantage of the extra reliability designed into the ZIP file format, such as 4-byte file header signatures and dual directory structures, to recover good files from damaged or truncated ZIP files. Other features include a deflating compression algoritym with varying levels of compression and speed, multi-volume archive support/formatting, and more. ------------------------------------- 7059/12007 PKZip-Related Utilities Small Programs Disk ------------------------------------- 2ZIP 2.1 Stanonik, Kelly $0-$5 converts .ARC .MD .PAK and .ZOO to .ZIP format, retaining the original file date too. It even converts .ARC files located within .ARC files, but only to one level. Req: DOS 3.1+ and 512k. Arc-2-Zip 1.5 (A2Z) McLean, Ian $0 will convert *.ARC and *.PAK files on your hard drive over to Phil Katz's ZIP format. Requires 384k RAM. Pascal source is included. UnZipII 1.1 FreeLance Programming $10 is an OS/2 UnZip utility for files created by Phil Katz's PKZIP archiving program. ZIP-2-ARC 1.1 (Z2A) Franklin, Bill $0 will convert ZIP files on your hard drive back to ARC files. Zip-Fmt PKWare ASP $0 is the file layout of ZIP files. Zipdel 1.0 Ted Stephens $0 cleans up a directory by deleting all files in the current directory that are also in a specified ZIP archive file, or vice versa. Pascal source code is included. Zipfile Date Stamper 1.1a (ZIPDS) Smith, Samuel H. $0 can be used to quickly update the date/time stamp on a bunch of Zipfiles. It also checks for truncated or garbled ZIPs (it does not verify the CRC, but still catches about 80% of all bad Zipfiles.) Pascal source is included. Zip ERase 1.1 (ZIPER) Moor, Joseph $0 will go through the specified ZIP file and attempt to delete all entries that exist in it in the current directory. It is very useful if you have un-ZIP'd files into a crowded directory and want an easy way to clean them out. ZiptMize 1.3 MJP Enterprises $0 will extract all files from a Zip and re-Zip them with the optimimum compression method. ZipNote 1.0 MJP Enterprises $10 allows easier adding of comments to ZIP archive files. Comments can either be typed from the keyboard, copied from an existing text file or stored in a configuration file. --------------------------------- END OF SMALL PROGRAMS DISK #12007 --------------------------------- ----------------------- 2033 PKZip Utilities #2 Small Programs Disk ----------------------- NOTE: Most of the files on this disk require PKZip or PKUnzip (on #1705). ArcToZip-HardDrive (A2Z-HD) Keber, Bob $0 converts ARC files into ZIP files, a subdirectory at a time. It has automatic zip file redating to the newest internal file date. Nzip and Whzip 0.98 (NZIP) Norton Associates $15 aid PKzip and PKunzip in finding archived files within any Pkzip file across all subdirectories on a disk drive, view selected files for inspection, and extract chosen files to any directory or drive. PKDate Gavin, Bruce $20-$30 is a ZIP file dating utility. It searches the specified ZIP file and identifies the latest file date and time. The date and time of the ZIP file is then set to match. PkInsert 6.1 (PKINSRT) 7th Illusion Enrg. $0 will let you insert a comment into a range of archive files. Other features include an integrity test, virus scan, disclaimer file insert/delete, and full activity logging. ReComment 1.05 (RECOMMT) Loewen, Michael C. $? is a ZIP file comment processor that will allow you to add, remove, replace and log ZIP file comments. It also allows you to set the ZIP file timestamp to that of the most recent file in the ZIP. StampIt Zimmerman, Bob $5 will update the comments in a ZIP file without changing the file date/time. Zipart 1.4 Gettys, Tom $5 breaks apart a ZIP file into a specified number of ZIP files of approximately equal size. It is easy to use and helps manage large ZIP files. ZIP Commenter 2.10 (ZIPCOM) Garzik, Jeff $5 comments ZIP files and does not put in a "brag line" like other ZIP commenters. ZIP Format View 1.0 (ZFV) Kaya, Raymond T. $0 allows you to see how a ZIP file is laid out on disk. It uses windowing to step down to lower levels of detail. It displays field offsets and most field values, including their interpretation. For the curious and those with a need to know, however, this program displays technical data on actual ZIP files. Zip Viewer 1.0 (ZIPVIEW) Bieber, Ronald C. $0 is a program for faster viewing of the contents of ZIP files. The program will also read self-extracting zipfiles without having to sift through 13K of self extraction code. C source code is included. Zview Brown, Ken $0 provides a listing of files within a Zip archive. -------------------------------- END OF SMALL PROGRAMS DISK #2033 --------------------------------- ----------------------- 3408 PKZip Utilities #3 Small Programs Disk ----------------------- NOTE: Most of the files on this disk require PKZip or PKUnzip (on #1705). Intelligent Rezipper 2.0 (REZIPPR) Colony Computer Services $15 is a PKZip enhancement utility. It allows you to scan for viruses, insert comments, delete files within a zip file, change the zip file date to the highest in the file, skip recompression on files with authenticity checking, and rezip a zip file within a zip file. SubZIP 2.1 Roberts, Greg $10 allows you to compress entire subdirectories into one file. It examines the subdirectory you specify, notes all file names and whether subdirectories below it exist, then ZIPs the entire contents into one single file using PKZip. All files are then deleted to free up space, but the directory structure remains intact. Requires PKWare's PKZIP and Vernon Buerg's LIST. UnZip 5.0 Smith, Samuel H. $0 will list, test, or extract ZIP archives. It is compatible with PKUNZIP 1.93 and has the advantage of being Freeware. Zip-Add/ZipEdit 1.04 (ZIP-ADD) P2C Consulting, Inc. $10/each makes it easier to Zip and UnZip files by letting you view a list of files from which to Zip/UnZip. It lets you see how much disk space you have available and how much space the unZipped file will take. Zip Chunker 2.01 (ZIPCHNK) Jibben, Scott $15 will split a large ZIP file into smaller ZIP files of a user-specified size. ZipNew Transversal Design $25 will make a ZIP file of any files changed within a time/date range. It is primarily designed for those who want to do backups of only the files modified on a given day. -------------------------------- END OF SMALL PROGRAMS DISK #3408 -------------------------------- Zip Comment Editor Boling, Michael D. $5-$10 #4353 allow editing and viewing of Zip file comments. Features include the ability to copy comments from another file, import comments from an external file, modify floppy volume labels, tag and untag files, write a list of filenames and comments to a file, view compressed zip file contents, delete single or tagged files from a zip file, import comments from a file stored in a zip file, sort files and more. ------------------------------- 1711 General Archiver Utilities Small Programs Disk ------------------------------- ar7 1.2 Erickson, Timothy R. $0 creates compressed archive files in straight ASCII which, unlike other archive formats, can be transmitted via email. ARC2PAK RGH Software $? is a utility program designed to search multiple hard drives, (C: through E:), build lists of all directories and subdirectories present, then, using that list as a reference, search each and every subdirectory on all hard drives to convert .ARC files to the .PAK format. Requires 384k plus DOS 3.1+. Archive Pruner 2.1 (APRUNE) Wisan, Richard N. $0 removes from a Zip or LZH archive all files that do not match files in the source directory. Archive Viewer 1.2 (AV-KL) Ledbetter, Keith ASP $0 will list the members of ZIP, ZOO, LZH, ARC, PAK, and PKA archive files, all in one swoop without having to call a different program for each. ArcSys 3.0 Moller, W.R. $5-$10 is a simple front-end shell intended to assist you in performing the basic functions of four of the popular archiving programs (PKZIP, PKPAK, PAK and LHARC). AZD 1.0 Copeland, Basil $0 is intended principally as a demonstration of how to scan and extract the directories of ARC, ZIP, and LZH files. TP4 source code is included. CVT 2.2 Starling, Kenneth H. $15 makes it easy to convert files from virtually any type of archive format to another. In addition, it will invoke ViruScan to check all de-archived files for viruses. CVT does not do the actual de-archiving and archiving itself. It works by invoking the required archiver, which must be present on your drive. It will permit the user to select the compression program and set their respective parameters. It also adds automatic search for all known archive extractors to provide alternatives for the extraction programs. The required archivers are available from PsL. CvtDir 1.2 Unique Software ASP $0 will convert any archive format to any archive format for an entire directory. MopARCHive 1.2r (MARCH) Gaulden, Dave $0 removes files from current directory that have been extracted from archives. It features a verification window to pick and choose the files you want to remove. Directory Xtra 1.0r, also included, displays a directory. Pulsar Ruffner, Richard D. $15 is a slick archive conversion utility that will convert any archive file format to any other archive format. It works by invoking the necessary archivers and dearchivers, so you still need the various utilities. It will also use ViruScan to check for viruses while it does the conversion. You can specify a preferred archiving format and Pulsar will always convert all other archive files to that format automatically. (The author can no longer be reached at the address listed in the documentation.) RView 2.46 Kaya, Raymond T. $0 lists directories of ARC, LZH, LZS, PAK, ZIP and ZOO archives, including self-extracting archives. Works by inspecting each file's internal format, regardless of filename extension. Besides being able to display archives in various ways, RV includes options to convert self-extracting archives back to normal archives, to strip excess bytes left at the ends of archives by modem file transfers, to reset the archive file date and time, and an option to help identify pre-implode ZIP files. X 3.0 Ledbetter, Keith ASP $0 allows you to combine seldom-used COM and EXE files into a command library file using ARC and then quickly execute them on command. Features include the ability to specify the drive where you want the program to place the temporary extracted file, the ability to store and execute batch files, and support for PKZIP. -------------------------------- END OF SMALL PROGRAMS DISK #1711 -------------------------------- -------------------------- 1712 Archiving Programs #1 Small Programs Disk -------------------------- Crunch 1.0 Byrne, Richard P. $0 will create archive files using LZW 12-bit compression that are compatible with those produced by PKWare and SEA programs. Pascal and assembler source code files are included. Disksq Graham Systems $0 will compress an 8- or 9-track disk into a DOS file which can then be sent over communications lines or stored for backup. The difference between this and a file archiver is that this stores all tracks, such as the directory and FAT, but not empty sectors. DWC A5.01 Cooper, Dean W. $0 is an archiving utility that is faster and creates smaller files than ARC, but is not compatible with ARC. PAK 2.50 NoGate Consulting ASP $19-$79 is a utility to create and maintain file archives in compressed form. PAK produces archive files that are consistently 50% to 90% of the size produced by either ARC or PKARC, and supports files created by either program as well as Zip files. The program also provides Temp path support for Network and worm drives. In addition, the full screen version is much easier to use than ARC or PKARC. Scrnch 1.02 McRae, Graeme W. $35 is a file compression utility for software developers. It creates a self- extracting file, similar to the way Phil Katz's PKARC utility does, but the file is normally much smaller. The disadvantage of SCRNCH is that it takes a LONG time to compress a file. (The extraction is very quick, however.) This combination of factors is why Scrnch is targeted at software developers who distribute many copies of the same program, rather than at the general public who may want to combine and compress files more routinely and quickly. -------------------------------- END OF SMALL PROGRAMS DISK #1712 -------------------------------- -------------------------- 4223 Archiving Programs #2 Small Programs Disk -------------------------- GNU Tar 1.08 (GNUTAR) Free Software Foundation, Inc. $0 stores files in an archive that may be written directly to a magnetic tape or other storage medium, stored as a file, or sent through a pipe to another program. Hap&Pah 3.0 Hamarsoft $20-$35 is a file compression/decompression utility. It supports multiple files, large files, and claims to be 30% faster than PKZIP. OCop Vass, Garry J. $0 will copy files to floppies with space optimization, verification, and optional use of PKZIP to archive the files. It will optionally copy the contents of all subdirectories in a specified path. C++ source included. KBoom Pawski, Miles $0 is a small, fast file compression/decompression program. Assembler source code is included. ST-EXP MicroComputer Square $25-$50 compresses and expands text files. The good news is that it even out- compresses LHarc by over 25%. A 122k text file was compressed to 57k by LHarc and to 40k by ST-EXP. Now the bad news: it only works on one file at a time, it cannot be used on non-text files and it costs $25-$50 to register (versus $0 for LHarc). Also, if you are compressing a file to give to someone else, with ST-EXP you have to give them at least the 30k EXP.EXE program with which to extract, if not the entire package. With LHarc, you can create a self- extracting file that requires no other software. So ST-EXP is not ideal for something like shareware distribution, but should be very worthwhile for those needing to compress text files on their own hard disk or for backup storage on floppies. ZOO 2.1 Dhesi, Rahul $? is an archive utility like ARC and ZIP (but not compatible with them). It does not create files as small as LHA, so we provide this mainly for those who may run across a ZOO file and need something with which to unarchive it. Also included is OOZ, a fast .ZOO file extractor. Extended multi-screen help is available. -------------------------------- END OF SMALL PROGRAMS DISK #4223 -------------------------------- -------------------- 1032 Archiver Shells Small Programs Disk -------------------- Since ARC has greatly declined in popularity and not kept up in efficiency, we will just briefly mention the names of these ARC-related utilities: AM 1.0, ArcAid 1.3, Lark 3.1, Narc 2.1, PKXTract 1.31 (PKX), PKARCM, ShArc 8.78. ARJShell 1.50 (ARJSHEL) Kellett, Andy $15 is a menu system for the ARJ compression utility. You can add or extract files within an archive, list files within an archive, check archive integrity, add or extract files with a password, set the compression ratio used, add or remove comments from an archive, capture comments to a text file, move files to and from an archive, and more. (Not on this disk. Ask for disk #8909.) Go-PsL 1.0 Ford, Nelson ASP $15 is a small (10k) software installation utility. It can be used by programmers to make it easy for users to install their software, or the enduser can use it to more easily review the purpose of archived files and to selectively install them. It supports LZH, ARC, ZIP and all self-extracting archives. It will install individual files or lists of files the user selects from a description file. (The GO.COM that PsL has begun putting on its disks is just a customized version of this program.) Sap 1.6 Andromeda Microsoftware $12 is a shell program that works with archiving programs to allow you to easily view, archive, unarchive, and convert from one format to another. SAP will display all files on a disk or in a subdirectory that are compressed files ending in .ARC, .PAK, .ZIP, .ZOO or .LHZ. -------------------------------- END OF SMALL PROGRAMS DISK #1032 -------------------------------- -------------------------- 3562 Mac Archive Utilities: -------------------------- FixSit Creative Bits $5 repairs the SIT files that are incompatible with UNSIT. UnSit 3.0 Uechi, Brian K. & Lau, Raymond $0 extracts files from a StuffIt file (files with an .SIT extension). StuffIt is to the Mac what ARC is to the PC. About the only use for this on the PC is for people who collect MacPaint picture files from Mac BBS's, since you cannot run MAC programs on a plain PC. It optionally tests for archive integrity and corrupt or incomplete files, and can handle decompressed file sizes greater than 2 megabytes. unPackIt 1.0 (UNPACK) McGinniss, R. (Scott) ASP $10 extracts files packed together on a MacIntosh computer with the PackIt utility. unStufit 1.0 (UNSTUF) McGinniss, R. (Scott) ASP $10 extracts files packed together on a MacIntosh computer with the StuffIt utility. -------------------------------- END OF SMALL PROGRAMS DISK #3562 -------------------------------- Archiver Comparison Cooper, Dean W. $? #1731 are the results and comments of the author's tests on several popular archiving programs: DWC, ARC 6.01 and 5.32, QARC, ARCA, PKARC, PAK, PKZIP under numerous options, and ZOO. ArcMaster 8.3 Newlin, John J. $35 #7472/1261 is designed to make it easier to work with archive files. It serves as a menu-driven, full-screen interface for command-line driven utilities such as Katz's PKZIP and PKZIP -t, for Buerg's ARCA/ARCE, for PAK and for LHA. Also supports LZexe, LZEshell, UnLZexe, and ARJ. Among its many features are the ability to tag files for batch ARCing or un-ARCing; automatic tagging of files by date; reading ARChived text files; optional deletion of orginal files after conversion; the ability to invoke ViruScan; to handle and view ZIP files with stored path information, and more. SHEZ 8.3 California Software Design ASP $39 #7472/2030 is a shell program to make viewing and working with archive files user friendly. Supported archiving utilities are PKZIP (including the option to only use the Imploding method of file compression, and creating Mini Self Extracting Files), PKPAK, LHA (LHarc), PAK, and Zoo. It has a tagged file display, a display of file sizes and dates, the ability to extract only newer files, sorting by file size, virus checking and mouse support. The program is DESQview aware, supports up to 200 directories, has the ability to Unsort the DOS directory listing, and has support for ARJ 2.10 self-extracting files. Other features include the ability to check nested files for viruses, a virus log file, keystroke record/playback, the ability to scan all files for viruses including SFX files, batch mode for SYSOP use, volume label support for ZIP and ARJ files, change compression method options, support for PKZIP prior to release 1.1, support for 4DOS/NDOS description files, a second pop-up directory window, XMS and EMS support, and support for ARJ 2.30 self extracting files, and more. Over 400K of disk space is required. ZipMaster New-Ware ASP $30 #7472/2593 is a powerful zip file compression system manager. It works with the PKWare file compression system programs PKzip, PKunzip, Zip2Exe, and PKzipFix. Support is provided for browsing files with Vernon Buerg's List, virus scanning files with John McAffe's Scan, and compressing executable files with LZexe. It makes navigation of a hard disk and its attendant directory tree structure a snap. It displays the directory structure of two separate disk drives as a graphic tree, 15 directories per page and all the directories are alphabetically sorted within tree levels of depth. Through the use of a movable cursor bar, function, alt, and ctrl key commands, the user may accomplish most directory management functions quickly and easily. The program includes the ability to display duplicate files in the inactive drive and directory that are duplicates of files in the active directory. Other features include support for ZIP files with DOS path names stored with the file names; the ability to print ZIP file listing, including any stored path information; the ability to change drive and select directory for all operations that require a drive:\directory destination path; the ability to manipulate a ZIP file that resides in a ZIP file: and sorting of ZIP file directory listing. ----------------------- 0272 Archiver Utilities Small Programs Disk ----------------------- Since ARC has greatly declined in popularity and not kept up in efficiency, we will just briefly mention the names of these ARC-related utilities: ARCA 1.27, ARCE 4.0e, ARCF, ARCV 1.21, ArcComp, ArcDel, ArcDmp, ArcfDate, ArcIndex, ArcSweep, Arc-Util, AV 1.3, Compr, MArc, Multi-Volume-Arc 2.0 (MVA), UnCMP 1.10, X 2.3, XArc, Xone2. Compr 2.0 Foster, Mark B. $0 is a set of small, fast utilities to simplify working with files that have been archived using a variety of different archiving programs. The utilities do not do the viewing or extracting; rather, they examine the file and invoke the appropriate archiving utility. You must have these utilities (eg: LHARC, PKZIP) in your PATH. The advantage is that you can always type the same command to extract files, for example, and Compr's XT will handle the details for you. Features include DL.COM which is a deleter for ZIP, LZH, LZS, PAK, ARC, ZOO, and DWC archives. Support is also provided for SH (shar), UUE (uuencode), TAR, Z (compress), SIT (stuffit), and PIT (packit) archives. -------------------------------- END OF SMALL PROGRAMS DISK #0272 -------------------------------- --------------------------- 12347 Archiver Utilities #2 Small Programs Disk --------------------------- Archive Sizer 2.01 (ARCSIZR) Jibben Software $20 is a file splitter that works with both regular and archived files. When splitting archive files, the new files that are created are fully compatible with the software that created them (if you split a ZIP file, the new files will be ZIP files). Archive Sizer supports ARC, ARJ, HYP, LZH, and ZIP archive formats. Other features include an option to delete the original archive file after successful file splitting and an option to create new archive files that will uncompress to a user-specified size. ExeMaster 2.5 (EXEMSTR) Smith, David $0 displays information about EXE and COM files, including archiver used, whether it is for DOS or Windows, whether it is a compiled batch file or self-displaying text file and more. EzCode 2.5 Hill, Charles $25 is a compression/decompression shell for PKZIP, PKUNZIP 1.1, LHA 2.13, PAK 2.51, ARJ 2.20 and ZOO 2.1. It copies, moves, deletes and searches for files; makes, removes and sorts directories; includes a text/hex file viewer with search and print abilities; and a cursor to count characters in text and bytes in hex. I See 4.2 (ISEE) Smith, David $0 is an archive shell which supports PKZIP 2.04g, PKUNZIP 2.04g, ZIP2EXE 2.04g, ARC, MKSARC, ZOO 2.1, PAK, LHA 2.13 and ARJ 2.39d. As a default, it determines which archiver was used on a file, then shells to the archiver to display the contents of the compressed file. Alternatively, you can invoke most features of the different archive programs using a standard set of command line switches with I See, such as adding or extracting files. Works on self-extracting files, too. Universal Archive Utilities 2.3 (UAU) Foster, Mark B. $0 is a set of utilities to make it easier to work with a variety of archiving utilities, such as LHA, PK-Zip, ARC, Zoo, etc. The utilities include an extractor, freshener, deleter, and file lister. They each work by determining what type of archive is being accessed and then invoking the appropriate archiving program to do the actual work. ZDiff 1.1 Dubourg, Christophe $20 is an archive/directory comparison program. It compares a pair of archives, a pair of directories, or an archive and a directory. It presents a sorted list of all the files and a status line showing the differences. --------------------------------- END OF SMALL PROGRAMS DISK #12347 --------------------------------- -------------------------- 0541 Old LU & SQ Utilities -------------------------- These are old utilities primarily of interest only to someone running into an old file compressed with one of these utilities, so we will just list the program names: Alusq, Lar13, LqType, Lrun, LSweep, LU86-43, LUE, LUT193, LUU, NUSQ, SQPC, SqluuSq2, USQ. 0541 "Trojan Horse" Utilities ----------------------------- HDSentry (HDSENTR) Fried, Andrew M. $? helps protect your hard disk from "Trojan Horse" programs while you test the program on a floppy disk drive. The program can read from a hard disk during testing as long as it doesn't try to do any damage. Naturally, no such program can be 100% foolproof, so you should still rely on regular backup procedures. NoHard Lambart-Ryan, Eric $? is for use when testing programs downloaded from bulletin boards that don't test their software. It keeps a possible "bomb" or "worm" program from writing to your hard disk when you run it. -------------------------------- END OF SMALL PROGRAMS DISK #0541 -------------------------------- ARJ Jung, Robert K. $35 #3122 is a self extracting archive utility that a produces smaller archive files (but not self-extracting files) than PKZip, PAK, and LHarc. In our testing, files that archived to 99k with LHarc archived to 91k with ARJ. However, when made into self-extracting archive files, the LHarc file only increased in size 1k to 100k while the ARJ file ballooned up by 15k to 106k. In addition, ARJ was painfully slow, taking over a minute to archive files that only took 30 seconds with LHarc, itself no speed-demon. However, ARJ offers a lot more features than does LHarc: support for multiple volume archives and for cross-platform archives; file security; the option to test a newly created archive before overwriting the original or deleting input files; selectable compression options including fast compression modes; multiple string searching within archives; 32 bit CRCs for file integrity; filename/wildcard exclusion; and the ability to recover files from bad archives. Other features include full ANSI C source code; extraction of archive header comments; the ability to handle merged multiple volume archives; an archive conversion program, REARJ; the ability to join archives; errorlevel support; caseless string search and context display options; volume labels; bar graph progress indicators; and more. File/Archive Marcor Enterprises $54 #1891 is for analyzing and archiving files on a hard disk. The program looks for files (of a specified type) which may no longer be active and offers to either remove them completely or archive them. If you have ever wished that you had the time (and determination) to keep old files cleaned off your hard disk, this is just the program for you. PALRun Pal Software $25 #2831 is an archive manager, DOS shell, enhanced DOS command line, DOS replacement, menuing system, and more. Archive management features include the ability to run executable files from within archives or from a subdirectory, edit or view files from within archives or subdirectories using your favorite editor and file viewer, and delete or inspect files. You can recall and edit previously executed commands either from a visible pick list, or by typing a few keystrokes and asking Palrun to fill in the rest from a prior command. You can also create on-the-fly batch files, issuing several different command with a single keystroke. The program helps you guess at an entire directory name after you supply just a few keystrokes, speeding up drive and directory changes. A customized menu may be created for executing common tasks. The Alias capability initiates a complex series of commands with a few keystrokes. Three-button mouse support is included. Hard disk required. ZIP'R 3.0 Stevenson Technical Services, Inc. $40 #4991 uses existing compression programs to compress directories, sub-directories, and the files they contain into one smaller, compressed file on a hard drive. This allows infrequently-used files to be stored in compressed form, saving a substantial amount of hard drive space. When a program is executed, ZIP'R invokes the proper compression program to decompress the desired directory, and executes the requested program. When the program is exited, ZIP'R invokes the chosen compression program to compress the entire directory. This technique will work even on disks compressed with Stacker and SuperStor. Supports LHA (on disk #1862), PKZIP (disk #1705), and ARJ (disk #3122). A network-compatible version is included. ]]]]]
