Clear recent files list
 

If you want to remove, edit or reposition some files from
File/Recent Files list

I think they are only stored in registry, so fire up regedit and get to
HKEY_CURRENT_USER\Software\Kinook Software\Ultra Recall\Recent File List

At least that's the location on my Win10.

Make sure UR is closed.

Then just doubleclick the registry keys for the list entries and delete or edit their content.

I didn't test this, but I'd not leave an empty key between two keys that contain a path.

Hope it helps someone :)
