By files, I assume you mean saves?
On Windows, it is possible as it also saves somewhere else
On anything else, I haven't a clue as I don't play this on Android, Linux, or Mac
(It would stand to reason extra files would also be made for each of these but you never know just search for Ren'py and saves should pop up)
(If you didn't save, play again with more saves or download a save from F95 or something)
