Your World and Player files (the actual save files on your computer where the Terraria application saves its data to) are stored in this directory:

Note: you can always create a manual backup of these files. (You do know how to copy a file on your computer right?) To revert to an older save state, you would just move your backed-up files back into that directory. This is also the recommended procedure for when save files become corrupted, which does happen on very rare occasions.

Terraria will use whatever save files happen to be in

So feel free to consider this as a manual save feature that is available to you. It even allows you to do things like downloading a world from online and play on it in single player, or ask your friend to email you his player file and then you could play as his/her character.

Just be careful when manipulating these save files, because if you lose or delete all of them, then you lose all your progress in the game...
