Selecting files to transfer from Steam Deck to PC After launching Warpinator and Winpinator, you can begin the file transfer process. Ensure both Warpinator and Winpinator remain open and connected.

A Steam Deck may be a handheld PC, but it's not necessarily obvious how to move files back and forth. You've got a few options.

On your PC, open File Explorer and navigate to C:\Program Files (x86)\Steam\userdata\. This is kind of a dumping ground for Steam’s files — even if you’ve got the game installed elsewhere.
