Right-click on part1.rar and select "Extract Here" . The software will automatically pull data from the other parts. Troubleshooting:
If you get a CRC error, try re-downloading this specific part as it may be corrupted.
Make sure all related files in the set are in the same directory.
Use the latest version of WinRAR or 7-Zip to avoid "Unexpected end of archive" errors.
Extraction will fail if any part of the sequence is missing from the folder.
