Introduction to WinRAR.exe Software

Developed by Eugene Roshal and maintained by RARLAB since 1995, WinRAR.exe remains the industry-standard solution for managing RAR archives and 20+ compressed file formats. This Windows-native utility (version 7.11 released March 24, 2025) provides military-grade AES-256 encryption alongside advanced compression algorithms that outperform ZIP by 8-15% in storage optimization.

Compatible exclusively with 64-bit Windows systems (7 SP1 through Windows 11 23H2), WinRAR.exe eliminates native OS limitations for handling files exceeding 4GB. The latest build introduces critical security patches against CVE-2025-31334 vulnerabilities related to Windows Mark of the Web (MoTW) bypass risks.
