You can just type "/s f_file ?" in the chat bar (without the quotes) and it'll bring up a dialogue. Anything in place of the ? will bring up the same dialogue, too. But yeah, just hop in-game with a random character first and check the Archive! Some years ago, characters were auto-archived after a set amount of time had passed. The recent vault wipe should have only affected low-level characters with very small file sizes, so if you had any characters with a bunch of levels and a bunch of stuff, they should still be there.
