For a visual walkthrough on how to properly install similar performance packs in FiveM, check out this guide:
: Distributed as a .rar file because this format is more efficient at compressing large game assets than standard ZIP files.
: Most packs require you to drag the extracted citizen folder into this directory, replacing the existing one. Always back up your original folder first.
: Since the file is a .rar archive, you will need a tool like 7-Zip or WinRAR to unpack the contents.
