in reply to System Command mv not working - Require a solution without modules.

Hello,

please add code tags to your post, see How do I post a question effectively?
probably you need to pass a full path to the command as "c:/users..." and(not noticed the linux directory output..) also note that the name DATA for your filehandle is a poor choice: DATA is __DATA__ (you can reopen it but is an unneeded risk)

Check your path, for example sourrinding it with square brackets and printing it, before using.
