Q: Can I compress files in multiple formats? A: Yes, WinRAR x64 4.00 RU supports a wide range of file formats, including RAR, ZIP, CAB, ARJ, and more.

Russian-language "repacks" often bundle registry keys that unlock the full version without payment. Distributing or using such modifications violates the WinRAR EULA and may expose you to legal liability in corporate environments. For personal use, the risk is primarily from malware, not litigation.
