 for %j in (*.jpg) > %{at}name[%j].txt

 creates zero-byte files.

 Wouldn't just setting UpperCase=Yes in the INI files accomplish
 that for display purposes?  (Unless you want it in more
 instances, or it's something HPFS does that FAT doesn't, in
 which case "for %f in (*.*) ren %f %{at}upper[%f]" might do it.)
