This one also failed... Let me try something else...
EDIT: small workaround, renamed the original ISO folder (which is empty apart from the undeletable folder) to something else (ms0:/Junk), and renamed the ISO2 back to ISO... Now, it's clean! But, the mystery continues... Also, I'm doing all these on Filer 6.6
EDIT2: The old renamed ISO folder (ms0:/Junk as mentioned above) can be deleted upon restart... Thanks for your input guys (especially Z).
