- DDUP.DOC: Documentation for DDup v1.1

-
- History
- -------
- v1.0 (Apr 17, 87):
- First release.
- v1.1 (August 14, 87)
- Accepts multiple filenames with exclusion list. New way to
- specify multiple drives command.
-
-
- DDup looks for similar files (according to options '/T', '/N' and '/S') and
- prompt you for deletion or renaming of duplicated files.
-
- DDup can act on three modes. On the default mode ('/T'), DDup look for twin
- files (identical name, size, date and time) and allows you to delete one or
- more duplicated files. Use this feature to clean-up your hard-disk by
- removing twin files.
-
- With option '/N', DDup look for files with identical names and *different*
- size, date or time. DDup will prompt you for renaming one or more files with
- identical names. Use this feature if you want to give different names to
- different files (see cautions below).
-
- With option '/S', DDup look for files with identical specs (size, date and
- time) and *different* names. DDup will prompt you for renaming one or more
- files with identical specs. Use this feature to trace identical files stored
- under different names (see cautions below).
-
-
- CAUTIONS: DDup do not verify the content of files but only their inscription
- in directories.
-
- With '/I' (default), take care before deleting a file. It is rare
- but files in two directories may have the same name and specs but
- being different files with different content.
-
- With '/N', rename files only if you are sure of their content and
- if you know that those files are not required by any program under
- those names.
-
- With '/S', be aware that it is frequent for two different files to
- have the same specs. Rename files only if you are sure of their
- content and if you know that those files are not required by any
- program under those names in their directories.
-
-
- SYNTAX: 'DDup drive(s):\directory\files [options]'
-
- 'drive(s)' drives to scan, eg: 'C:' or 'CDE:', default is current
- drive.
-
- 'directory' to scan from, default is current directory. To scan
- all a drive, specify the root directory '\'.
-
- 'files' to scan, wild cards allowed, default is all files
- '*.*', multiple filenames (eg: '*.COM+*.EXE+*.BAT')
- and an exclusion list after a slash (eg: '*.*/*.NOT')
- are allowed.
-
- 'options' '/T' (default) to look for twin files with identical
- name, size and date-time and prompt you for deletion.
-
- '/N' to look for files with identical name but different
- specs (size or date-time) and prompt you for renaming.
-
- '/S' to look for files with identical specs (date-time
- and size) but different names and prompt you for
- renaming.
-
- '/D' for discrete scanning, '/H' for help,
-
-
- LIMITS: DDup can scan an unlimited number of files on an unlimited number
- of drives simultanously. Of course, DDup is limited by the RAM
- available. It can handle more than 2,400 files per 100k available.
- It should be quite enough for 80 megs of storage with 640k systems.
-
- DDup can prompt you for deleting or renaming up to 20 duplicated
- files. If you have more than 20 duplicates of the same file (or
- name/spec), you will have to run DDup again.
-
-
- USES: C>DDUP Default use, scan for twin files down from the
- current directory on the current drive.
-
- C>DDUP \DIR\*.* Scan all files of \DIR and its children
- directories on the current drive.
-
- C>DDUP CD:\ /S Scan all files of drives C: and D: for
- duplicated specs.
-
- C>DDUP \*.ARC+*.DAT Scan all *.ARC and *.DAT files of the
- current drive.
-
- C>DDUP *.*/*.COM+*.EXE Scan all files down from the current
- directory except *.COM and *.EXE files.
-
- C>DDUP /D /N Scan discretely for duplicated names.
