How to open by OS

Windows

  • WinRAR, 7-Zip (read-only).

Mac

  • The Unarchiver, Keka.

Linux

  • `unrar` or 7-Zip.

Ios

  • iZip, Documents by Readdle.

Safety notes

  • WinRAR's historical ACE-decompression CVE (CVE-2018-20250) allowed remote code execution. Keep WinRAR patched.
  • Password-protected RAR evades corporate mail scanning and is a common malware delivery vehicle.

Common mistakes

  • Forgetting to enable recovery records means a single missing split makes the whole archive unrecoverable.
  • RAR is proprietary — for distribution, ZIP or 7z is usually friendlier to recipients.
