If your computer still doesn't know how to open it, right-click -> "Open With" -> Choose 7-Zip or WinRAR.

While RAR files are secure, they can contain viruses. It is highly recommended to use an antivirus to scan files before extraction.

Before opening, right-click the extracted folder and select your antivirus software to scan for threats.
