Where are unsynced Dropbox files stored on an old SSD?

I'm going to post how I managed to recover the files for whoever might find it useful, although I'm unsure *why* this worked.

I used recovery software to comb the NVME drive in the enclosure and then recovered the entire user directory into a backup folder on my computer. It wasn't even an actual Users folder I copied it into, I mean it was quite literally just a folder.

The process to comb and recover the folder took quite a while, but once done: Bam, magically on my Quick Access bar did the Dropbox folder of the past just appear. Even though the files were in no way in any actual Users, Windows, etc folder and just a random floating folder in my new drive, there the files were. When I tried to locate the files themselves, it needs to be stressed that there was no Dropbox folder, and there were none of the files findable by name, but simply recovering the files into a random empty folder did this.

The process of recovering made Windows have a bit of a fit as it kept randomly detecting 'viruses' then deciding they weren't with Defender, like a spooked deer.

Once they appeared (and I can't even find them via the appeared folder, but they are there and I can interact with them via Explorer) I copied them out to safely secure them while I still could. This seems to fall in line with my theory that Dropbox's folder actually exists more like a cache somewhere with some sort of tags. The files did not exist in an actual searchable state until I made that ephemeral folder appear and copy them out.
