- DUPLICATE FILE LOCATOR v3.11
-
- Welcome to DFL. If you are running the installation program, you can print
- any of these documents by hitting <F2> while viewing them. Help can be
- obtained by hitting <F1>.
-
- ---------------------------------- Summary ----------------------------------
-
- DFL provides a complete pulldown menu system with context help to allow you
- to find and process duplicate files.
-
- - DFL will find duplicate files by any of these 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.
- Dos Path - DFL will search the Path for duplicate executables like DFL.EXE,
- DFL.BAT & DFL.COM.
- FastAlias- Files with duplicate contents are found using a 32 bit CRC and
- filelength combination. Filenames are ignored.
- FullAlias- Files with duplicate contents are found using the 32 bit CRC and
- filelength combination followed by a byte-by-byte binary
- comparison. Filenames are ignored.
-
- Ex. Sysops find that one of the many uses for the alias modes is
- to find all those BBS advertizing files that have been
- embedded in their archives. It's nice to tag all of them and
- hit one key to make them go away.
-
- - The files can then be:
-
- Viewed.
- Deleted.
- Printed.
- Compared in either binary (internal comparison) or ascii (user-customized).
- Tagged and group-deleted.
-
- - You may specify a filemask such as *.* or *.exe.
- - DFL will scan multiple drives including network drives.
- - The duplicate list can be printed to an ascii file or printer.
- - Virtual Memory is created and cached to allow the proccessing of huge
- numbers of files. About 1 meg of disk is needed for every 25,000 files.
- - DFL can be run unattended from a batch file.
- - DFL will perform all of the above operations for files in any type of
- archive. DFL can be customized to run with up to 10 archive compression and
- extraction systems of your choosing. DFL is pre-cusomtized for ZIP, PAK,
- LZH, PKARC, ARJ, ARC by SEA and ZOO.
-
- More detailed discussions follow...
-
- ---------------------------- TO INSTALL AND RUN -----------------------------
-
- Assuming you're logged to the directory that contains the DFL files (listed
- below) -
-
- Type: INSTALL (or A:INSTALL if the DFL files are in drive A:)
- Hit: <ENTER>
-
- The install program will search for previous copies of DFL and prompt you for
- the directory to copy DFL311S.EXE and DFL.SAV. This should be somewhere on
- the DOS PATH. Install will optionally rename DFL311S.EXE to DFL.EXE
- (recommended).
-
- Once installed on the PATH, to run DFL -
-
- Type: DFL (or DFL311S if not renamed)
- Hit: <ENTER>
-
- That's it!
-
- -----------------------------------------------------------------------------
-
- This group of files is the latest shareware version of DFL. The compressed
- file DFL311.ZIP should contain the following files:
-
- DFL311S.EXE - The shareware executable program
- DFL.SAV - The default configuration file
- DFL.DOC - The manual
- ORDER.DOC - The program registration order form
- DFLREAD.ME - Read Me file with misc. notes
- WHATSNEW - List of new features.
- VENDOR.DOC - Information for vendors.
- INSTALL.EXE - DFL installation program.
-
- After reading these documents, the only files you should need to keep are
- DFL311S.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 that we
- provide with the REGISTERED version. The only difference between the
- shareware version and the registered version is that the shareware version
- has opening and closing registration reminder screens.
-
- DFL uses a proprietary technique to create 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
- more discussion on the Virtual Memory System.
-
- Thanks to the Virtual Memory, DFL only requires about 340K 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 (user-customized) 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 Alias regardless of archive type.
- - DFL can handle up to 10 archive types of your choosing.
-
- In addition to supporting archives, the other features of DFL which we have
- not found in any other similar program are its ALIAS modes of operation.
- Using these modes, the contents of equal-length files, archived or not, are
- examined 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.
-
- DFL will also find duplicate files by any 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.
- Dos Path - DFL will search the Path for duplicate executables like DFL.EXE,
- DFL.BAT & DFL.COM.
-
- 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, 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 by about 14k. We stopped packing the distributed copy after running
- across a cache program and some multitasking software which rendered it
- inoperative. Please don't upload EXEPACKed copies, or for that matter, copies
- other than exactly what was downloaded or otherwise obtained.
-
- DFL311.EXE compresses very well (50-60%) with PKLITE, LZEXE and other similar
- executable compressors.
-
- We recommend that you rename your copy of DFL311S.EXE to DFL.EXE for typing
- and memory convenience.
