Subject: Folder Synching & Removing Dups

Folder Synching & Removing Dups

Windows folder synchronization and duplicate file removal is handled
differently by various software. It's easy to generate multiple files
named identically in different folders which contain the same song by
the artist but from different performances. Typically (but not always)
these will have different file lengths. So a first screening test for
identifying duplicates would be to look for identical file names. A
second minimally required step for prudence is to compare file sizes.
While only an exhaustive and agonizingly slow byte for byte file
comparison can guarantee that files are 100% identical, comparatively
fast "hatch mark" mathematical comparison screening is an intermediate
step that "Space Hound 32" allows as a screening option. That is a very
high standard. By comparison, "PowerDesk 5" ran a folder comparison
which generated a "duplicate file" list which contained many identically
named examples which WERE NOT EVEN THE SAME SIZE! So before following
automatically generated advice about what "duplicate" files to delete, I
suggest that you make sure you're using software that does more than
perform a naive file name comparison in generating a duplicate file
candidate list before accepting that advice by pressing delete.
