Thanks for your reply, I appreciate it!
No, there is no network drive involved. I did more testing and i can replicate the problem reliably.
Also, I don't think general tags are the problem, but the unknown binary tags of serato, which contain information about waveform, cuepoints, sub-dcimmal bpm etc. They are displayed the following way in tag view:
GEOB <unknown Data Type>
To reproduce I do the following:
1) I have a set of mp3s in Folder A. I load them into the DJ Software. Everything works as expected.
2) I use the Move,rename,copy Files command to Folder B
3) Some files from Folder B cannot be loaded into DJ Software anymore, until I strip Tags and rescan.
Again, I can provide copies of the affected files. You can even download scratch live for free and replicate the error on your system (though I doubt seeing serato crash would provide any insight
The Files are still playable in Other Software. Serato crashed while trying to read the content of the Tags.
