X1c Clean Audio Folder STILL not usable!

Clean Audio Folder STILL scans through every single directory, on every single mounted drive on my PC.
 
There is no reason for this. The audio path is explicitly stated in the form, and my settings declare I am using per-project audio folders.
 
Last night I installed X1c and, full of hope, I tested it.
 
When it starts, there is no way of stopping it. No Cancel button; nothing.
 
I sat there watching helplessly for a full 25 minutes as it scanned and scanned and scanned.
 
In the end, it found my Windows service pack .tpl files and said they were unreadable and were created by a different application. Why is it even looking in \Windows\ServicePackFiles\i386?
 
I do a lot of dragging and dropping of externally edited wav files and need to clean up regularly.
 
Yes, I know, creating a new project and copying is a workaround; but it would be great if the Clean Audio Folder utility could finally be fixed and brought up-to-date.
