Gotcha, well it’s something to try I guess.
On SSDs with TRIM enabled it will eventually erase deleted files, unlike a mechanical disk where the data still exists until it is overwritten. But that doesn’t really matter because the recycle bin will be on the disk that the files are on, so it will be on the SD card, unless I’m mistaken about how the recycle bin on Windows works.
Nope you’re right, I actually wanted to note this earlier but forgot. Depends how he’s doing it though, if he’s watching and deleting the files on the SD card, of if he’s moving the files to the PC first.
