I just tried to rename my files and directories with tag2file. This worked fine.
I used this pattern:
%genre%\%artist% - %album% - %year%$num(%track%,2) - %artist% - %album% - %title%
What I figured out now is follwoing. While the data files are being moved to the new directory structure all my "folder.jpg" albumart files remain in the original directories. At hundreds of albumarts it is close to impossible to copy all of them manually.
Is there a way that I could script? a directory name change (with tag2file) + folder.jpg transfer + (optional) old directory removal??
