In that situation, *long* filenames can be processed by using my library
"Lfn.zip" from the user contributions page.
Instead of
   system("del "  & bkname, 2)
   system("copy " & name & " " & bkname, 2)

one has then to write
   system("del "  & short_name(bkname), 2)
   system("copy " & short_name(name) & " " & short_name(bkname), 2)
