: Use a dedicated utility such as WinRAR (Windows) or The Unarchiver (Mac).

: Right-click the first file (usually Part 1) and select "Extract" or "Unpack." The software will automatically link all parts to reconstruct the original data.

: Unlike ZIP files, Windows and macOS do not have native support to open RAR files; you generally need third-party software like WinRAR , 7-Zip, or The Unarchiver.
