I have a folder full of files, with a number of duplicate files in it. Unfortunately, in a number of cases, one version is an updated version of another, so a straight byte-match doesn't locate the duplication. (I've looked at this question, but all the one I've looked at from the list seem to only do byte-count comparison...)
Are there any (Windows) dedup applications that can do a similarity-match and point the user to the files in question for examination? Freeware is good, free trial is acceptable. Even just a list of similarities to tell me where to look would probably work.
EDIT: Sorry, I should have mentioned; these are text-based files, primarily DOC, PPT and PDF. The most likely thing to have changed is the content, but formatting might differ as well. Even just picking up on text changes would probably be helpful though...
