you can try DOS command "ren", for more information, you can type
'help' in dos window
Files with a filename extension dl_ are, as the extension implies,
incomplete so renaming won't work and more than simply copying to a different
directory would. It has to be expanded from its compressed state on the CD
or in the SP directory and the way to do that is with the expand command in
what looks like an old DOS window in XP. As has been posted, you bring that
up by typing cmd in the Start>Run box and at the C:\ prompt type expand
D:\i386\???.dl_ c:\Windows\System32\???.dll where D is your CD and i386 is
the folder on that CD containing the file you want and where System32 is the
target folder for the newly expanded file.
