Export to Album Folders v1.0 – This script will export and sort the files of selected tracks into Album-named folders in the Finder. Or, optionally, the files can be exported/sorted to Artist folders and Album subfolders. The selected tracks needn’t be pre-sorted; the script will use each selected track’s Album (and perhaps Artist) tag to construct the folders. Might be handy for SD card users.
For OS X 10.6 or better.
