Edit the list of previously opened files?

When I opened pspad today and went to File->Open Special/Recent, I noticed a few files that no longer exist. I figured that there should be some way to edit the list and get rid of a few of the files listed. However, I found nothing, saw nothing in the registry, and when I searched the pspad directory, I did not find the file list there.

If this can be done, would someone please tell me how. Thanks.
