I do this all the time. You just create a simple BAT file and add it to the VI job on Job Success. Here is one I recently used. It appilies a time stamp and moves the file.
If exist U:\TimeTest.xls rename U:\TimeTest.xls WOTime_%date:~4,2%%date:~7,2%%date:~10,4%.%time:~0,2%%time:~3,2%%time:~6,2%.xls
'for /f ""tokens=1-5 delims=/ "" %%d in (""%date%"") do rename ""U:\TimeTest.xls"" WOTime_%%e-%%f-%%g.xls
