If any part of a solid archive—like Part 2—is corrupted, it often makes all subsequent parts or files impossible to extract. How to Use This File

Right-click part1.rar and select "Extract Here." WinRAR or 7-Zip will automatically pull the data from part2.rar and other subsequent volumes as needed.

Because data is treated as one continuous block, you cannot extract files from the middle of the archive without processing all preceding data.
