Hi @shmimel,
I see what you mean, and this sounds like an issue with how DJay manages offline files.
Maybe a built-in duplicate detection feature would be a good addition for DJay to implement—something that identifies and removes duplicate tracks automatically or at least flags them for review.
This also could add up with a request I made for a ‘Not in Playlists’ view, which would help identify tracks that aren’t assigned to any playlist to identify tracks that might still need to be assigned to one of your playlists or deleted from the database.
Both improvements could complement each other in making library management more efficient don’t you think?
