The .rar format is a proprietary archive file used for data compression and recovery. Inside this specific archive, one would typically find:
Check Hashes: If a checksum (MD5/SHA256) is provided by the source, verify it to ensure the file hasn't been tampered with.
Scan Before Opening: Always run an updated antivirus scan on any .rar file before extracting its contents.
Data Folders: Containing assets, textures, sounds, and scripts.
