There are 56 files in Resident Evil 3, and when you find one for the first time, you'll need to scroll all the way through its pages to the end to get credit for discovering it. Many of them also contain useful information like safe combinations or key item locations, so it's worth keeping your eyes open for them.
As with other collectibles in RE3, your file-collecting progress is saved directly to your profile on the spot whenever you find and read a new one. You do not have to find and read all 56 files throughout a single run through the game. However, the game is very linear, so you only have one shot at collecting most of these files before they become unavailable for the rest of that run.
Notably, the four "tutorial" files that you gradually unlock as you play through the first stretch of the game are stored in your Files menu, but they do not count towards this record.
Please note that this guide to collecting all 56 files will unavoidably contain minor spoilers for the game's later locations and fights. You're better off using this to clean up after you've already beaten the game at least once.
This list of the files is numbered in rough accordance with the order in which they appear in the game, for organization's sake. This order bears no resemblance at all to the order in which they're stored in your in-game inventory menu.
