A RAR file is a compressed archive data container. It holds one or more files and folders inside it, reducing their overall size for easier sharing and storage.

So why are they packaged like this? The original PlayStation 3 Blu-ray discs can hold up to 50 GB of data (for dual-layer discs). Distributing a single file of that size would be impractical for several reasons. Many file-hosting services impose strict file size limits, often capping uploads at 1–2 GB per file. Additionally, if a single 50 GB download corrupts halfway through, the user must start over from scratch—a frustrating experience.
