In Rockstar’s naming convention, mp stands for (GTA Online). The numbers follow a YYYY-MM format.

Most vehicle mods, map mods, or weapon packs are distributed as a dlc.rpf inside a folder (often named after the mod). To install them:

If you want to add a new vehicle as an “add-on” without touching mp2023-01 directly, create your own DLC pack (e.g., mods\update\x64\dlcpacks\custom_cars\ ) and reference it in dlclist.xml . This is safer and more organized.

3D models ( .yft ) and textures ( .ytd ) for the cars introduced in that update.

Rockstar Games updates GTA Online by dropping isolated content folders into the dlcpacks directory. The directory name mp2023_01 translates to Multiplayer Update 01 from the year 2023.

By following these steps, you can ensure that the mp2023-01 update files are properly maintained, allowing you to enjoy both official content and custom modifications.

: Your dlc.rpf grows to an unusually large size after repeated modifications. Solution : Use OpenIV's "Defragment" function on the dlc.rpf to clean up unnecessary data and reduce its size.

After updating, launch your game and open the in-game internet (Home key). Look for the "Warstock Cache & Carry" or "Legendary Motorsport" ads for 2023 vehicles (like the Entity MT or Issi Rally). If they load textures correctly, your update is successful.

Once the launcher repairs the native update/x64/dlcpacks/mp2023-01/dlc.rpf file, you can safely copy it back into your mods folder via OpenIV.

Before attempting any modification, you must install , the definitive archive editor for GTA V.
