3 Questions from an Old player.

Hallo guys, I recently reinstalled the game 3.23 for no:

• My game character, hours of customization, is gone I cannot load it, is there a way or a folder to find out the save file and back up it?

• Same question as above but for the keybinds

• How the hell can I put things on the ground into a container?

• How the hell can I switch the prospector bag with the argomento ones? I can buy and spawn them on the Elevator but how can I mount them without going out In space? Is there a way?

Thanks so much
