I searched all the subject lines in the open discussion forum for "dup" and did not find any discussion regarding deduplication. Granted, I believe one can accomplish deduplication with some custom comparison (only show files that are equal, use CTRL+A (Windows) on one ...

I also suggest a probe variant on Ed's proposal (or yet another option) which is to examine both the first AND LAST chunks of a file when comparing files. This is especially useful for comparing rolling log files that are truncated to a fixed size.
