What are ".itc" files? Keep getting created at every iTunes session
I've found out that my computer now holds about 800 files with the extension .itc (the names are all something like 135576F762524B0B-6DBC1D9D023F9661.itc) and this number keeps getting bigger with every iTunes session. These files are created in the My Music/iTunes/AlbumArtwork/Local directory. Also, every iTunes start up takes longer and longer, as every .itc file is scanned during start up while the message "updating iTunes library" is shown".
Can these files be safely deleted? What exactly is going on, as this did not use to happen before?
