My path is \\Lizzy\Media (M)\Music.

My library is now chalk full of duplicates:

\\Lizzy\Media (M)\Music and
\\LIZZY\Media (M)\Music

That never happened before and I'm not sure how to fix it.

I don't want to do a search for \\Lizzy or \\LIZZY and remove the results in case a file in the result isn't a duplicate.

Nor do I want to search for duplicates first and then remove one or the other. The reason is simple. If MC now sees this as two different files such that it felt the need to re-import it, then one of them has all the correct tags from the database, and the other, the most recent import, might not.


I really don't know what to do.

You could sort by date imported.

Filenames should be case insensitive on Windows, so I'm not sure how this would happen.  Any tips to reproduce?

Ok, I think I know what happened but I'm still not sure why duplicates were created and maintained.

I had made some tag changes on my laptop library. 
I created a playlist of all the songs I had changed, and exported it.
I then imported it into the main computer.

I thought that only the differences in tag info would be updated, but instead MC created new instances of each song.
Hence the duplicates with the exact same filename but different tags.
Oh my, what a mess. I didn't realize that importing a playlist would actually create duplicate entries of the same track if it already existed.

What type of playlist, MPL?  Also, how did you import it?

I just exported my whole library to MPL, then dropped the MPL on Media Center and selected 'Import'.  It imported 0 new files.

Yeah, it was mpl, or at least I'm pretty sure it was as that's the only type of playlist I ever create. I don't have the playlist anymore, though, just whatever is under "imported playlists" and it has a "play" icon like my other mpls so I assume it was that.  It was done Feb 1 and Feb 2 so it's possible there was a bug with MC at the time, I don't know.

I think I'm about to remove all audio files from the main library and the import an mpl from my laptop, but before I do I have one question: should auto-import be turned off when I do this? I can just see MC starting an auto-import of all my music files while I'm importing the playlist and I'll just get duplicates again.

[Matt]

Auto-import combined with manual import still shouldn't produce duplicates.

I tried manually editing the case in an MPL using UNC paths and still couldn't get duplicates.

If you figure out how to reproduce duplicates, please let us know.
