Yes, I'm not so sure about the output of "ls" myself. (note the 'a'
where I would expect an 'x' for the file) I did try the
attrib command, but it only showed that the directory is "system"
and the file is "archive". Also, I created the file via under my
account (ls shows owner = Philip) and I can delete it manually with
"rm" or "del" or with a perl script just fine. I also tried using
"os.unlink(d)" with the same results. I found another command
lsacl to list the access control list, it gives this: (YOGA is my
workstation name)

C:\>lsacl border-l-r2-c3.gif
