Some tracks not exporting to USB

Hi everyone,

So basically I’ve just noticed that some of my tracks aren’t exporting to my USB stick. The collection on my Engine DJ software shows all of my 1050 tracks, and on my USB stick collection it only shows 1014 tracks.

I’ve tried dragging and dropping the songs directly into the playlists on my USB stick but they still won’t move over. I’ve also made a playlist to drag everything into as a backup and I’ve done that from day one, but they still won’t move.

Before I go through the process of reformatting my flash drive, I’m just wondering if anyone knows a solution?

Just a quick edit: I’ve still got 88GB left on the flash drive
