You cannot "play" or "run" Part 25 on its own. To access the contents, you must:

If Part 25 is missing or corrupted, the entire extraction will fail. Make sure you have the complete set from the same source!

Use a tool like WinRAR or 7-Zip . You only need to right-click on part01.rar and select "Extract Here." The software will automatically "stitch" Part 25 and all other pieces back together into the original full-sized file.

It significantly improves the compression ratio, making the final file size smaller.
