Lost Permissions Can't Delete Folder
If you're on an admin account, you should be able to click the lock, supply password, then click the + sign &amp; add yourself as read/write.
If it won't let you do that, then try on the next folder up the hierarchy, setting permissions to at least add yourself as read &amp; write, then click the 'gearbox' icon &amp; 'apply to all enclosed items'.
