1. If I Uninstall Toribash, will it delete my account or replays?
2. How do I get my replays into a folder? When I downloaded the game, it didn't create a folder...

1) Yes, so make a backup folder if you ever intend to do so.

2) Your Toribash replay folder is located in Toribash - Replays in your C drive.

so basically,
You won't lose your account, but you will lose your replays
C:>Games>Toribash>Replays
If you dont know what C: is, then just open my computer and hit local disk drive, or hard drive.

1: i think your replays will be deleted, your acc wont be deleted.
2: usually it's in c:/games/tb/replays; there you can see all your replays.
hope it helped
