Bug ID: 46505
           Summary: cmd.exe: rename file from upper to lower
           Product: Wine
           Version: 4.0-rc6
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: cmd

If I want to convert a file to lowercase (or vice versa), 
I can do it under Windows with:
  ren FILE.BAT file.bat

Under Wine the file is still in uppercase.

Workaround in Wine:
    ren FILE.BAT FILE.BAT.tmp
    ren FILE.BAT.tmp file.bat
