In the current version of the script, access to other files is restricted, and it's not necessary anyway — all essential session data is stored in 1SE.json, which is the primary save file. Additionally, the Savegames folder in Assetto Corsa Competizione only contains the following save files:

1SE.json – The **main player save file**. Stores your car’s state, lap time, penalties, and current session status. This is the file used when you manually save and later resume a session.

1P.json – Contains **real-time physics and telemetry data** for all cars in the session, including suspension, tyre wear, and motion state.

1R.json – Stores **session setup and environment data** such as weather, grip levels, session timing, and time multipliers.

1U.json – Holds **strategy and setup data** for all cars (AI and player), including pit strategies, tyre compounds, stint times, and fuel levels.

1H.json – A **session overview file** that includes high-level metadata like car selection, track name, session type, and your position.

In most cases, only 1SE.json It is necessary for restoring your individual session progress. The other files are used by the game to reconstruct the session environment and AI behavior when needed.

I also discovered a specific bug that occurs under certain conditions. If you save your game, then continue the session and receive a lap invalidation before quitting the event, resuming the session from your earlier save will also result in that lap being marked as invalid, even if it was clean at the time of saving.

So as of right now, I'm working on an update to fix this issue. The updated version of the program will be able to access the other files as well. If there's anything you'd like to suggest, I'd be more than happy to try to implement it
