Right-click on Part 1 only . Select "Extract Here" or "Extract to Postal.4...". The software will automatically pull data from all other parts to recreate the full game folder. You do not need to extract the other parts individually.

Once extraction is complete, open the newly created folder (usually named Postal 4 No Regerts ). Run the Game:

Ensure Postal.4.No.Regerts.v1.1.0.part1.rar and all subsequent parts (part2, part3, etc.) are in the same folder .

Look for Postal4-Win64-Shipping.exe or simply Postal4.exe in the root folder.
