Go to this folder: Start --> Documents --> My Games --> Terraria

You should see 2 folders, Worlds and Players.

Inside the Players folder, create a folder called tConfig and copy your player files into there. Inside the Worlds folder, create a folder called tConfig and copy your world files into there. You can now use your worlds/players with the Reborn Mod.

Note: Make sure you have a backup of your world and player files. Once you pick up mod items and the game is saved, that save won't work with standard Terraria again. So it's important to back up your worlds/players before you mod.
