Thank you I will look into it and post the new code with the next version which will include a recover mode so that you can redo the renaming. This would make it easy to use the more descriptive filenames e.g. when writing the files back from a cd-rom.

But I think just skipping a filename would mess up my list which has to be in the same order as the list with the original names doesn't it? I like the idea of the ~X method though. Thank you very much
