I've tried a few, but need something that knows, for example, a *.DOC and *.DOCX are the same file
same with *.MP3 and the various music formats.

I did searche Google and AVS, but there's quite a bit of experience on this group more in line with my preferences.

Most duplicate file finders look at more than just the file name. In your .doc vs .docx file example, the files would also be different sizes do to different metadata etc. So what you're looking for is a dupe finder that only looks at file names and allows you to map file extensions to ignore differences? I haven't seen any prog that can do that.

I use Auslogics Duplicate finder which works great even for files with different file names/extensions or dates. However, unless your .doc and .docx file are bit for bit identical and just happen to have different extensions, I don't think you'll find a duplicate finder that can identify them for you.

There are plenty of music management software for identifying similar audio files based on metadata (e.g. if you have a track in multiple formats: flac, mp3, wma, m4a, etc). However, if you save the same document in say, Microsoft Word 97~2003 format (doc) and Microsoft Word 2007 format (docx) which are two completely different formats, you're probably on your own.

Of course as a one-off exercise you could just search for all files of certain types, then sort by size and manually find dupes. This may be very tedious though and if you had the same song in FLAC and mp3, you wouldn't spot it (for example).

Music is easy. There are plenty of music management software you can use to sort them (assuming your metadata and ID3 tags are in order).

It's having, for example, doc, docx, odt, pdf, etc versions of the same document that becomes tedious.

I'm going to give this one a try. Thanks.
