- ==============================
-
- The FINDDUPS program allows you to generate a list of all duplicate files
- over any number of hard disks. It can cope with very large disks with a
- large number of files. The report generated is very simple - each group
- of identical files is printed, separated by a blank line from the next.
- The first file in each group also shows the file size (of course, all
- files in the group are the same size!)
- At the end of all the lists, the total number and count of duplicate files
- is printed. These totals do NOT include the first file in each group; the
- idea is that you will want to keep one copy of the file, so only the
- duplicates are "wasting" space.
-
- Usage is FINDDUPS drive_list [drive_list]
- Where: drive_list is drive_letter[-drive_letter]
- and drive_letter is a valid drive ID.
-
- e.g. FINDDUPS A: looks for dups on drive A: only
- FINDDUPS C-E: looks for dups on drives C:, D: and E:
- FINDDUPS C: E-F: H: looks for dups on drives C:, E:, F: and H:

- NOTES:
- ------
- * This program (and it's sources) are public domain.
- * The program can take a long time to execute, especially on very large hard
- disks. Also, very large duplicate files (especially if there are several
- duplicates) can significantly slow the program, since the entire contents
- of the files need to be compared to check for duplication.
- * The program works in two parts; firstly, it creates a list of all files
- on the disks, and then it looks for duplicate files. There will be a lot
- of disk activity during the second phase if there are many duplicates!
- * The program may run out of memory if you have a truly enormous number of
- paths and files. An error message will be displayed if this happens.
- * The list of duplicates generated may be quite large. It is probably a good
- idea to redirect the output to a file, and then use an editor (or "MORE")
- to look at the results. (eg FINDDUPS C-E: H: > output.doc)
- * A quick and dirty way to delete any unwanted files would be to edit the
- redirected-output file and then give it a .BAT extent.
- * The C++ source is available on CIX.
