peter Deleting a song in the app should also remove the audio file. I don't need a video yet and will see if I can reproduce it myself.
Ahh, oops! Regarding removing of files, I was looking in the Stage Traxx 3 folder and not the Stage Traxx 3 Beta folder. Files are being deleted there, so that's not an issue. What fooled me was that the entire folder gets deleted after I delete all songs, so I could only see the non-beta folder.
So now only the errors during importing still remain...
