WinDiff is still awesome and it works perfectly fine in Windows 10, but no Unicode support. Please hold on! Don’t be taken aback by the year of the initial release. WinDiff is a graphical file comparison tool from Microsoft which was first released in the year 1992 and subsequently updated.

Once everyone's happy you can move the original data to a safe place (i.e. Remove any empty folders ( for /d %i in (*) do rd '%i' will do that for you), use your best judgement to eliminate any remaining program components, and then get the client to check each remaining pair of files by hand and pick whichever one they prefer. Here's how I'd do it: Make a copy of both folder trees, then use your favourite deduplication tool (I like CloneSpy, but then I also like Marmite) to remove all the identical files from one of them. I think you and your client are going to have to get your hands dirty. You probably don't want to be on the hook for those kind of decisions. Anyone capable of getting into this mess is equally capable of making conflicting changes to copies of the same document, of making a trivial change to an old file which changes its timestamp, or even of preferring an older version to a newer one.
