: The filenames must be identical except for the "part#" suffix. If any are named differently, the extraction will fail. Start with Part 1 :

: Right-click on MWCN22.part1.rar and select "Extract Here" or "Extract to MWCN22/" using WinRAR or 7-Zip .

: Ensure you have MWCN22.part1.rar , MWCN22.part2.rar , MWCN22.part3.rar , and so on, in a single folder.

: Use The Unarchiver to open the first part; it will automatically find and join the subsequent parts.

: Use the RAR for Android app, locate the folder, and select only the first part to begin.
