Because part files are often used to distribute large, unauthorized, or pirated content, they frequently appear on file-sharing sites. It is highly recommended to scan any RAR file with antivirus software before attempting to open it [2].

You need software such as WinRAR (Windows), 7-Zip (Windows/Linux), or The Unarchiver (macOS) to extract the file, provided you have all the parts in the same folder [1, 2].

Such files are almost exclusively used for sharing large datasets, software, or media, broken down into smaller, manageable chunks [1].
