Hi,
I used the trial version of Switch to convert mp3 files from iTunes to wav for a cd, having forgotten that iTunes burns audio files.
The result is a folder on the desktop which won't be deleted (locked). If I try to delete individual files in the folder I am asked for my admin password, but then I get the message that I 'do not have sufficient privileges for some of the items'. I burned these files to a CD-R but they wouldn't play so I threw it out. Maybe this is an Apple issue, if so sorry to trouble you, except I can't find anything about these privileges.
Kind regards
JohnM
