So I installed some games on an external HDD to play on my tablet. I want to move one of them back to internal storage. It's Fallout 3, and I've installed some mod/tweaks. What's the easiest way to move the game back to the internal Steam folder? I don't want to have to reinstall and go through all that bullshit mod/tweaking again, and I'm worried verifying game cache files will fuck up my modding.
