_Batch CP conversion_ OK. I think Encoding menu will be good place for batch encoding conversion
I don't replace original files during conversion, but folder with .OUT suffix on the same level as original folder is created and converted files are stored into same directory structure there. It allows you simple copy into original location after check. Another possibility is create individual files backup... -- <http://forum.pspad.com/read.php?2,67953,68097> PSPad freeware editor http://www.pspad.com
