When large files are broken down into smaller, manageable chunks for easier uploading or downloading, they are named sequentially (e.g., .part1.rar , .part2.rar , etc.). How to Handle Them:
Use tools like WinRAR or 7-Zip on the .part1.rar file to decompress the entire set.
You must have all parts of the archive (part 1, part 2, etc.) in the same folder.
Changing the file names can cause extraction errors. Security Warning
