steam deck and full pc game files

[Jeeper1986]

Hello guys, Im in a bit of a pickle, just go a steam deck and i want to move the games from my pc that arent steam games.

I was able to move a whole installed game on my pc to a memory card and transferred it to the steam deck now my issue is the lunch file thats on my pc is no longer present on the steam deck file that I moved so I can not lunch the game from desk top mode.

also when I come to add the game folder in to the steam app it wont allow me to select the whole folder any help with this?

Did you copy it or cut it? If you copied, it should have no effect on the PC version.
