well i found it just fine. here is the list
of all formats recognized by photorec in their wiki. Once you start photorec and have selected the hard disk you want to work with it will ask you which partition you want to do the recovery on. In the very bottom of that page there is a [File Opt] choice where you can make the selection of formats you want or dont want. Just choose 'unselect all' and then select the ones u want using the spacebar with them highlighted. Then continue on as usual.
