DUPLICATE FILE LOCATOR PROGRAM Version 3.01
This group of files is the latest shareware version of DFL. The compressed
file DFL301.ZIP should contain the following files:
DFL301S.EXE - The shareware program with self-contained help.
DFL.SAV - The configuration file.
DFL.DOC - The manual.
ORDER.DOC - The program registration order form.
DFLREAD.ME - This Readme file.
After reading these documents, the only files you should need to keep are
DFL.EXE & DFL.SAV. All the help information can be accessed on-line. Over
the past few years, you won't believe the number of DOC/TXT/README files
I've accumulated ( or would you ? ) and had to keep around in order be
able to use a program a month later.
Nevertheless, the extended documentation manual is included as the file
DFL.DOC. It contains information and tips that may be helpful while
running this newer, more complex program. The manual file is the same
manual as we provide with the REGISTERED version. The only functional
difference between this version and the registered version is that the
registered version has full support for all file archive systems we are
aware of. Also, refrain from trashing ORDER.DOC until you have thoroughly
explored the program. Our support for registered users IS worth it.
With this version of DFL we introduce Virtual Memory. By caching to disk
as it processes, DFL can handle an 'unlimited' number of files. Previous
versions scanned until they run out of memory at around 8000 files. The
internal data structures used to capture the contents of the disk are as
small as can reasonably be expected. Depending on how many directories you
have, it is safe to assume that DFL will require about 40 bytes of disk
space per file. Based on this, DFL should be able to handle approximately
25,000 files for every megabyte of free disk space. Please consult the
manual for a complete description of the Virtual Memory System.
Thanks to the Virtual Memory, DFL only requires 320K of memory to run. So,
some of the more advanced functions that require spawning to other
programs can now be performed.
Enter, stage left, Dos Shell, File Compare and COMPLETE ARCHIVE SUPPORT.
Dos Shell speaks for itself. The File Comparison program may be used by
DFL to examine in detail the actual differences between any two files.
And, by COMPLETE ARCHIVE SUPPORT, we mean:
- Archives are treated as regular directories. The files within these
directories can be manipulated in every way that normal files can. This
includes:
- Archived files can be deleted.
- Archived files can be viewed.
- Archived files can be compared to other archived or normal files,
in either binary (internal comparison) or ascii (external
comparison using FC.EXE) regardless of the type of archives in
which they reside.
- Archived files can be tagged and group-deleted.
- Archived files can be processed by every DFL Scan Mode including
Name, Partial Name, Length or Content (Alias) regardless of archive
type.
- DFL can handle up to 10 archive types of your choosing.
- Archive support is available to registered users only.
- We offer 30 day money-back satisfaction guarantee.
In addition to supporting archives, the other feature of DFL which we have
not found in any other similar program is its ALIAS mode of operation.
Using this mode, the contents of equal-length files, archived or not, are
compared to identify duplicates. The file names play no role whatsoever.
For example, this will allow the user to locate files such as PROGRAM.C
and PROGRAM.BAK which have the same contents but different names. This may
also be of use to sysops who want to weed out duplicate uploads or semi-
duplicate archives which contain the same files, but have a comment or
something to hide the overall archive as a duplicate. Using alias mode, I
was able to free about 20megs of disk space on one my drives.
DFL will also find duplicate files by one of these other Modes:
Name - DFL will find files with identical names.
Length - DFL will find files with equal lengths.
Name1-11 - DFL will find files with the first N matching name letters.
As should be expected from any half way interactive system, complete
context sensitive help is available, as well as an extended online manual.
The idea is that, as stated above, you should never need to look
elsewhere for assistance while running the program. However, for
registered users with archive support, there are some situations during
the initial definition of an archive format that can be a little tricky.
DFL comes with several predefined formats, but when adding one of your
own, you may need to consult the more extensive manual or call us.
You may use MicroSoft's EXEPACK.EXE utility to decrease YOUR copy of the
program EXE by about 14k. We stopped packing the distributed copy after
running across a cache program which rendered it inoperative. Please don't
upload EXEPACKed copies, or for that matter, copies other than exactly
what was downloaded or otherwise obtained.
DFL.EXE compresses very well (50-60%) with PKLITE, LZEXE and other similar
executable compressors.
