: You need third-party software like WinRAR (the native format creator) or 7-Zip (a popular free, open-source alternative).
: Right-click the .rar file and select an option like "Extract Here" or "Extract to [Folder Name]".
: Be cautious when downloading .rar files from unknown sources, as they can sometimes be used to hide malware or viruses. Always scan downloaded archives with antivirus software before opening them.
