I was helping the OP in CB and we just lost contact for some reason. The first issue was: what do you want to do? And that appeared to be move all .pdf files in one directory to another directory. One issue was "moving" files between file system mount points (which is a copy and delete). We never got to this .rtf file point. But that would have been the next question: how do you get this list of files to move and to where?

So I second your question.
