.rarファイルとは？

RAR (Roshal Archive) is a proprietary archive format known for its superior compression ratios compared to ZIP. Created by Russian software engineer Alexander Roshal, RAR files typically achieve 10-30% better compression than ZIP. RAR also supports advanced features like multi-volume archives (splitting large files), solid compression, recovery records, and AES-256 encryption. While creating RAR files requires WinRAR, many free tools can extract them.
