I figured it out. I temporarily renamed my 8830 folder to 8100 (copy the original name if it has the version number, etc, or zip up a copy of it). When I ran the tool Spectral made, I answered all of the prompts, and then let it clean out the folder. It took it down from about 350 files to about 260. Some of the files couldn't be found.

After running the script, I renamed my original folder it's name, and ran the Desk to Manager. It cleaned out a few files.
