I was installing non steam games on my Steamdeck through Lutris, I then decided to uninstall a game I no longer needed and saw that 60gb was successfully deleted (don’t ask me how). Please if a Linux user can help me recover the files I will be extremely grateful.

I know of a software called “testdisk” but I have no idea how to use it. Can someone reach out who has an idea how this works please. Thanks.

EDIT: The files for saved to my SD card.
