: Windows 11 now includes native support for opening .rar files directly in File Explorer.

: Right-click the file labeled part1 or part01 .

If the file ends in a sequence like .001 , .002 , ensure you select the .001 file to begin the process.

: Choose "Extract Here" or "Extract to [Folder Name]" using tools like WinRAR or 7-Zip .

: If the native tool fails with multi-part archives, specialized software is more reliable:

: Ensure every part of the archive (e.g., part01.rar , part02.rar , etc.) is located in the same folder. Missing parts will cause extraction errors.

: The software will automatically read through all subsequent parts and combine them into the original single "piece" (file or folder). Recommended Tools for Windows 11
