- RV-RView, Version 2.44 07-May-92
-
-
- Directory lister & utility for ARC ARJ LZH LZS PAK ZIP ZOO. Rewritten and
- redesigned in a different language from 2.43 (not simply translated). User-
- configurable to display either ZIP- or LZH-style compression ratios.
- Listings may be sorted by Name, Extension, Date, Original size, Packed size,
- compression Ratio, or left Unsorted. New option to supress listings
- completely. Also includes a possibly one-time, limited, scrollable version
- of RView.

- ===========
- RView and this documentation are offered as is. The user bears the entire
- risk of this software not performing as expected.
-
- Purpose:
- ========
- To provide a single, stand-alone program capable of listing directories of
- several archive formats. Filename extensions are ignored in determining
- archive types.
-
- This utility also contains various features not conveniently provided
- elsewhere at the time of their inclusion.
-
- RView is a free program.

-
- The type of archive is displayed before listing each archive. For
- self-extracting archives, the letters "SFX" follow the name of the base
- archive type. The program further distinguishes between small- and
- large-model LZH SFX archives and shows which ZIP SFX's are of the "Mini"
- (Junior) type.
-
- For ZIP 2.0-type archives, the three different variations for "deflating"
- are reported as "Deflate", "DeflateX" and "DeflateF" for Normal, maXimal and
- Fast compression, respectively.
-
- Compression ratios ("CR") computed by RView are of two types:
-
- ZIP-style (default):
- --------------------
- 100 - ( PackedSize / OriginalSize * 100 )
-
- LZH style:
- ----------
- PackedSize / OriginalSize * 100
-
- The date and time indicated on the "totals" line represent the date and time
- of the most recently created or modified member of each archive. These are
- the values used by /R in resetting the archive date and time.
-
- RView displays the total number of bytes required to contain the listed
- files if extracted to a selected drive. If no drive is selected, the drive
- containing the archive being listed is used. In making this computation,
- RView takes actual disk cluster sizes into account.
-
- Syntax:
- =======
- Usage: RV [switches] archive [d:] [file...]
-
- Switches may appear in almost any position on the command line. '-' may be
- substituted for '/' wherever DOS allows.
-
- An archive name specified without an extension will result in a search for
- all extensions. Thus typing "RV filename" is equivalent to "RV filename.*".
- Also, "RV *" is equivalent to "RV *.*".
-
- An optional drive may be included immediately after the archive name to
- check for extraction sizes to the indicated drive.
-
- Example: RV backup.lzh a:
-
- Result: Causes RView to compute extraction sizes for drive A:.
-
- File specifications following the archive name will limit the listing to
- only those files matching any of these specifications.
-
- Example: RV source.zip *.h *.c
-
- Result: Causes RView to list only C header and source files
- contained within SOURCE.ZIP.
-
- Switches:
- =========
- /A Alternate compression ratio. ZIP-style compression ratios are
- displayed by default (see above). Using this switch display
- LZH-style ratios. (Tip: Include this switch in RV.CFG to always
- display LZH-style ratios.)
-
- /B Brief filenames. Use this switch to suppress the display of full
- pathnames, i.e. only the filename.ext parts of full pathnames will
- be shown.
-
- /C[file] strip/attach zip file Comment. Strips file comments from ZIP
- files. If a valid filename immediately follows "/C" (no
- intervening spaces), then comments contained in that file will be
- attached to the specified ZIP file(s).
-
- /D sort lzh and zip files on Disk. LZH and ZIP files are written
- back to disk in the order implied by the /S family of switches.
- Nothing is done for already-sorted archives. Sorting to disk is
- available so that LZH and ZIP files will be displayed in sorted
- order by listers that don't do in-memory sorts. Also,
- disk-sorting is useful for LZH files when telops ('!' files) are
- used.
-
- /I Ignore rv.cfg file. This option was added by user request
- to provide a means of overriding the defaults specified in
- RV.CFG.
-
- /P Pause display after each screenful. After pausing, pressing
- almost any key causes another screenful to be displayed.
-
- /Q Quiet (suppress) listing. Added by user request to speed file
- processing by BBS SysOps.
-
- /R Reset date and time of archive. The date and time used will be
- those of the most recently created or modified file in each
- archive.
-
- /Sx[-] Where 'x' represents N/E/D/O/P/R/U, as follows:
-
- SN - Sort by Name (default)
- SE - Sort by Extension
- SD - Sort by Date/time
- SO - Sort by Original size
- SP - Sort by Packed size
- SR - Sort by compression Ratio
- SU - leave Unsorted
-
- Appending a hyphen '-' to the above switches will reverse the
- sense of the sort from ascending to descending.
-
- /U[path] Un-sfx self-extracting archive. Converts self-extracting (SFX)
- archives to normal archives. A new file will be created with the
- same name as the SFX file but with the appropriate extension
- (".ARC", ".LZH", etc.). The normal archive is written to the
- current directory by default. "/U" followed immediately by a
- valid path (no intervening spaces) allows writing to the
- specified target drive/directory.
-
- /W Wide display format. Displays up to five names per line.
-
- /X strip eXtra bytes from end of archive. XMODEM-type file transfer
- protocols often pad transferred files with added bytes. This will
- truncate ARJ, LZH, LZS, PAK and ZIP archives to reflect their
- "true" sizes.
-
- Keyboard commands:
- ==================
- By user request, beginning with Version 2.34, the single-key,
- program-pausing feature has been added back. While RView is displaying an
- archive, pressing <Esc> will terminate execution. Almost any other key will
- pause the display. After pausing, pressing <Esc> will terminate execution.
- Again, almost any other key will resume execution.
-
- Configuration:
- ==============
- An optional configuration file containing user-selected default switches may
- be created or edited with any editor or word processor which can write pure
- ASCII text files. This file should be named "RV.CFG" and placed in the same
- directory from which RV.EXE is loaded (DOS 3.0 and above).
-
- Switches, including switch options, may either be separated by spaces or
- placed on separate lines.
-
- Incompatible switches used on the command line will override switches
- included in RV.CFG. Switches are evaluated from left to right on the
- command line.
-
- A sample RV.CFG file is included in the distribution archive for RView.
- After extracting the contents of the distribution archive, RV.CFG may be
- deleted if RView's defaults are satisfactory.
