MP3Tag v 3.26 64 bit - Windows 10 Can someone verify if this is the way MP3Tag should work? I load my library Highlight all files Open Extended tags I make no changes, but each time I hit "OK, it "Saves", and writes to the Mp3 tag. (I made no changes to the MP3's, just viewed them....) I ca…

[image] telrod11: it thinks there has been a change to the entire library. Are you sure that there is a real change inside your files? Or does only the timestamp change? Do you see a difference if you create a hash from some test files (with MD5 or something similar) before and after you cl…

[image] LyricsLover: changed hashes yes, that would be an indication.

@LyricsLover I just ran a small test, using the "Preserve file modification time", and MP3Tag did perform for me, as I thought that it should when I click OK. No changes that my backup software recognizes. I then selected a group of files, and made a change to one of the tags, and again, my backu…

[image] telrod11: For me, this change works, and I thank you for the help! Thank you for your feedback. Please keep in mind the use case @ohrenkino mentioned: For files loaded the very first time it could be that even if you don't change yourself anything in your tags they could by changed …

Yes. OK saves the current tag data back to the file.
MP3tag does not compare the current tag data with a possible previous state.
