realistbyte You didn’t mess anything up. It’s just that Windows File Recovery is a weak tool, plain and simple. Just try Disk Drill, it’s way better. Launch it, select your system drive, and let it scan.
Once the scan is done, you’ll see a search bar at the top, type .rtf there and it should show you all recovered documents with that extension.
Also, before downloading, you can change the location of the Downloads folder in your browser like others suggested. Maybe it’s not a big deal at this point, but it couldn’t hurt.
