On several occasions I have had files and folders ( that were copied from a
workstation to the server using AFP ) that have been unable to be deleted.
Depending on where you try to delete them from you get an insufficient
rights, folder not empty, or file in use message for the reason that the file
or folder is unable to be deleted.

Does anyone have an idea what causes this AND just as importantly, how do I
delete these undeletable files and folders?

Thanks in advance.
