Wow, I would never have figured this method out on my own!
 
It took some 15 minutes to scan my C drive and for the Find button to reappear.
I stupidly selected only one orphaned file, just to test.
After I pressed Move, I got the "re-scan" message without the option to continue moving files.
All dialog boxes went blank and it now compels me to do a re-scan, which will take another 15 minutes.
 
I do appreciate the information, but I think my workaround method is faster.
By the way, how the heck did you figure all of that out? I don't know if any mere mortal would even know what CWAF means.

Yes, copying a project to a new location is the quickest way to clean a single project, but I mess around with a lot of different projects over short periods of time, and like to be able to clean everything at once periodically. CakeWalk Audio Finder works well for that.
 
Step-by-step procedures for even the simplest operations always look more complex when written out; just try writing a procedure for tying your shoes.    Using the "Excluded Waves" folder is just a trick to allow archiving files for a while to avoid the extremely bizarre fringe case that there might be a problem down the line because your files are arranged like a madman's breakfast.   Otherwise, you can just delete them and go on your merry way.
 
I have a dedicated top-level "Cakewalk Projects" folder at the root of the drive with all other paths excluded from the scan. I haven't timed it, but It would guess the scan takes 3-4 minutes. I have a huge number of projects/versions accumulated over the years, but maybe proportionally fewer audio files because I work mostly with synths and don't always render every track separately, so my scan might be faster. But, yes, you'll want to move all the orphans at once because each move necessitates a re-scan. If my system took that long to scan, I would move old, unchanging projects to a separate "Archive" path that I could exclude, and only clean recently active projects.
 
 
 
 

Not fixed. Cakewalk said they will fix it a few months back when I supplied a screenshot, but would not say when it would happen (fair enough). Personally I wish they would remove it until this happens.

@avalanche - thanks!
@brundlefly - No, it really is complex. Two tools, doing the same thing, in the same menu, complicated and non-intuitive, one best started stand-alone... crikey.
I record live bands, so I have lots mostly orphaned clips because I edit a lot and couldn't be bothered to copy the project and rename it yet again...
It would make much more sense if one could simply say which directories it SHOULD scan. Then it would be just my cakewalk projects folder.
 

I forget the semantics of each, but another issue is I save multiple iterations of the same project, so even though files may be linked to a cwp in a folder, they are orphaned to the final cwp. Save as is simplest to another folder, but with HDDs being big and cheap these days I only clean up video files anymore.
