Locates duplicate files in a directory or a directory tree (-r) basing the
comparison on the file contents and ignoring the file names.
Common usage is importing pictures from camera media and wishing to determine
whether the files have been previously imported and possibly renamed.

Groups of identical files are displayed, and optionally (-d) erased.
When both source and destination parameters are provided, duplicates are
removed only from the source.

Zero size files are ignored for erase as they are always identical and the file
presence can have meaning outside of their contents (common with .ini files).

When deleting (-d) with recurse (-r), the code will remove empty directories.
A directory is considered empty when it has no files, or when it has only files
of zero size and in this case, the zero size files are purged with the directory.

Syntax:
    finddups [-switches]  [Destination] [Destination] ...

Where
    Source      Directory path and optionally filenames, wildcards supported.
