I use autofs to mount samba shares. On one computer was the music share removed. The problem is that it is impossible to unselect this share. I get a grey checkbox on the computer name, but when I expand the catalog nothing is selected (this is not that surprising since the share is removed). How do I remove this catalog from the collection?
Is the collection catalogs stored in the database?
Can I access the database with mysql?

I think that I would get the same effect if I add a catalog. Import files from that catalog into the collection. Turn off amarok and remove the catalog and it contens and start amarok again.

I am currently trying to add the hole computer and then I am going to remove it.

You should be able to change the collection folders configuration here:

$HOME/.kde/share/config/amarokrc

Thankk you, that was what I looking for. Hovewer, I do not know I it would have worked, because I had to reboot the computer and after that it started to work agian
