RAR (Roshal Archive) is a proprietary file format developed by Eugene Roshal. It is frequently used because it often provides a higher compression ratio than the more common ZIP format, making it ideal for large datasets or multi-volume archives.

: Compressed files are often used to hide malware or viruses from basic antivirus scans. Always ensure your antivirus software is active and consider scanning the archive with a tool like VirusTotal before extracting its contents. WinRAR download free and support: WinRAR

: To open a .rar file, you typically need third-party software. Popular options include WinRAR (the native creator), 7-Zip (a free, open-source alternative), and PeaZip .
