Major Update.
I found my files. All of them. And they have the proper filenames and file information on them.
When I first set up this new computer I resassigned the default location of "Music", Video", "Pictures", "Document" folders in the Quick Access area of Windows Explorer from C:\ drive to E:\ drive as I didn't want this stuff being written to my C:\ drive.
When OneDrive was doing its (unauthorized) backup of my E:\ drive it must have run into an issue with my E:\ drive and sent the User Folders (Pictures, Documents, etc.) from the E: drive back to their original default home on C:\Users\YourName.
Well, today I didn't want to store anything on my E:\ drive, including Music, Pictures, Documents, Videos, so I reset the Quick Access setting to default. That's when I noticed I had 15GB in my C:\Pictures folder. That was way too much. So I took a look inside the Pictures folder and there was EVERYTHING.
Here's how Gemini described it:
What happened: During the update, Windows likely encountered an issue with your E: drive (probably due to that "Waiting for Activation" BitLocker state). To prevent data loss, it "redirected" your User Folders (Pictures, Documents, etc.) from the E: drive back to their original default home on C:\Users\YourName.The "missing" 5,000 files were actually sitting in this local folder the whole time, but your Quick Access was still pointing to the "broken" links on the E: drive. By clearing the Quick Access cache, you forced Windows to point back to the active, working folders on C:.
Now I will not need to preview each file of the 5,400 files that Recuva found and decide if I wanted to keep it or not. I've got them all back.
There is some cleaning up to do with my E:\ drive. I might end up reformatting it, not sure.
