Title: Random duplicate files
Post by: crisp on April 30, 2025, 03:46:08 am
Hi. I've started seeing random duplicate files. The filenames are identical. There seems to be no rhyme or reason to it: sometimes it's a whole album, sometimes a handful of tracks within an album. It occurs across two separate external hard drives.

One thing I have noticed is that when I highlight a file and its duplicate, the tag File > Filename shows as "varies". But toggling between them reveals no difference to my eye.

I'm aware that I can manually remove duplicates, but this would involve picking through a large database and I'd like to identify the source of the problem rather than embark on a time-consuming exercise. Besides, I can't tell which is the duplicate and which is the original.

I'm using MC32.

PS these are not multiple albums (eg Beatles in Mono and Beatles in Stereo). They are duplicate tracks in MC occurring in single unique albums.

EDIT: The only tag difference I can see is between import dates, eg on one example we have:
1st one: Date Imported 06/04/2025 15:40:19
2nd one: 23/04/2025 09:55:49

Check the location tag.

Could be decomposed vs precomposed UTF-8 character handling. There are some threads in this forum about that, I think there's a fix tool somewhere to fix/convert all filenames in your disks.

Thanks but I can't find any thread that might relate to my issue and I don't want to dive into areas I don't understand.

I can't find the "location tag" in tags.

Update: as a test, I launched an older version (MC26), imported the files into the same library and the problem didn't occur.

OK so as an experiment I backed up my library from MC26, then bought an upgrade to MC33, then restored the library from the M26 backup.

EDIT Did "Run Auto-Import Now" and the doubles all appeared, import date now 01/05/2025

So I don't know what to do

I've done some more research on yabb and think I've made a bad mistake. Several weeks before this issue occurred I moved my audio files from a single EHD to two, which of course meant changing the file path. I have just read this thread:
https://yabb.jriver.com/interact/index.php?topic=134520.0

I realise I should have followed these instructions when I did the move. All I did was auto-import. Now all my files (including the duplicates) have the new filepath.

However, I have the library backup from before I moved the audio files. Can I revert to that library and follow the "Rename, Move, and Copy Files" from there? Do you think that would work?

Sure.
