Dupefind is Synchronet's file de-duplication utility. It will (at least) report duplicate filenames but it will not report if the same content is in different files.

By default, dupefind will scan all your configured file libraries. You can limit the scan by specifying starting and/or ending file library numbers.

Dupefind is exec/dupefind on *nix systems and exec/dupefind.exe on windows systems.


usage: DUPEFIND [start] [end]
where: [start] is the starting library number to check
       [end]   is the final library number to check
