Format Details
RAR
RAR (Roshal Archive) is a proprietary archive format developed by Eugene Roshal that supports high-compression ratios, strong encryption, archive splitting across multiple volumes, and built-in recovery records for repairing damaged archives. It uses a specialized compression algorithm that often outperforms ZIP for many file types. RAR archives are widely used for distributing large software packages and are commonly encountered in file-sharing communities.
7Z
7Z is a high-compression archive format associated with the free, open-source 7-Zip archiver. It uses the LZMA and LZMA2 compression algorithms to achieve significantly better compression ratios than ZIP and RAR, often reducing file sizes by 30-70% more than competing formats. 7Z supports AES-256 encryption, solid compression, multi-volume archives, and can handle files of virtually any size.
