How to clear FiveM cache step-by-step

To clear the FiveM cache step-by-step, follow these instructions:

1. Close FiveM completely, ensuring it is not running in the background.

3. In the data folder, locate the cache folder.

4. Delete the entire cache folder.

5. Additionally, delete the folders named server-cache and server-cache-priv if present.

6. Optionally, also check and clear files in %localappdata%/FiveM/FiveM.app/logs and %appdata%/CitizenFX if needed.
