I don't use iTunes and I won't ever. How do I block iTunes from creating the folder
~/Music/iTunes/Album Artwork/Cache?. I can't find the background process that is responsible for it.
Thank you for your time.
Remove write permissions from yourself.
It is also created when QuickLooking an MP3 file (not always, but twice for me in two hours) -- I'd say it's futile (if it's just QuickLook, you can workaround that using Finder Get Info preview).
