This is my reg file: Windows Registry Editor Version 5.00 [HKEY_CLASSES_ROOT\*\shell\Burn con Nero] [HKEY_CLASSES_ROOT\*\shell\Burn con Nero\command] @="F:\\PROGRA~1\\Ahead\\nero\\nerocmd.exe --write --drivename g --underrun_prot --close_session --force_erase_disc --underrun_prot --enable_abort --use_allspace --artist %USERNAME% --real --iso \"%1\" %1" it adds an entry in context menu, for all files, like "burn con Nero". So if you right click on a SINGLE file/directory it starts nerocmd.exe and burns that file to a CD/CD-RW , if you put the switch --dvd it's the same but for DVD/DVD-RW. The problems now are two: 1)it doesn't work if the file/directory has a name with spaces, nerocmd can't find the file and give you an error such "file nont found" or "file mismatch" 2)if you select TWO OR MORE files/directories it only burns one of them i tried to change the final %1 with %* as suggested but nerocmd doesn't burn at all telling me " file not found". If you put *.* instead of %1 no matter if you select only one file, it burns ALL the files in that directory. Any help will be very appreciate
