I have a big musicfolder on my Windows Home Server which i'd like to tag with musicbrainz picard. For some albums when clicking on Save, the whole album fails to do so with "Errno 13" and doesn't move to the specified Folder.

First i thought it would be because the music is on the server, but moving it to a local hard drive didn't work, as well as testing the program running directly on the server. I then edited the folder permissions to full access for everyone, user "Jeder" in german which didn't change anything. Running the program as administrator didn't change anything either, except drag and drop failing.

The following appeared in the log for every file of the problemalbums, in this case with the album on the local harddrive D and changed folderpermissions to everyone:
