FOR %%i IN (?) DO call move.bat %%i 000000%%i
FOR %%i IN (??) DO call move.bat %%i 00000%%i
...

move.bat:
move /Y srcdir\%1 destdir
ren destdir\%1 %2

**** OR even better ******
FOR %%i IN (?) DO ren %%i 0%%i
FOR %%i IN (??) DO ren %%i 0%%i
FOR %%i IN (???) DO ren %%i 0%%i
FOR %%i IN (????) DO ren %%i 0%%i
FOR %%i IN (?????) DO ren %%i 0%%i
FOR %%i IN (??????) DO ren %%i 0%%i
FOR %%i IN (???????) DO ren %%i 0%%i

*** both methods assume there are only files to be converted in the directory
