in der Datenbank legt mAirList Ordner an, die im System nicht vorhanden sind (sie Screenshot).
Die Tracks in diesen Ordnern spielt mAirList dann nicht ab.
Woran kann das liegen?
Most of us have no clou what your asking
Sorry Henk, I didn’t know that mAirList went English by the time. I am using it for quite some years now and whenever I had a problem before the message always was German. But hey, no sweat – switching to English.
The mAirList databank is creating subfolders as you can see them in the screenshot. Its doing this completely by itself – there’s no script or something for that and it all started just a few weeks ago.
mAirList puts tracks in that folders and these tracks are not played anymore.
As you can see as well, these subfolders are not existing when you look at the directory outside the mairlist databank.
I simply do not know how to prevent mairlist creating that folder chaos. 
I do understand now 
but sorry no answer.
MAirlist didn’t go English you just post your post in the English section.
On top you have English forums
Then Deutsche foren (German)
And other languages Nederlands /Dutch
When you click Synchronize and select which type, you need to de-select the Preserve Folder Structure.
See screenshot,
