: Go back to the website or folder where you obtained parts 1-3.
: To extract the full video, you must have all numbered parts (part1, part2, part3, etc.) in the same folder. If you are missing part 4, you generally need to re-download that specific file from the original source where you found the others.
In the context of multi-part compressed files, "complete paper covering" is not a standard technical term. It is likely a mistranslation or a request for:
: This specific file name follows the naming conventions of unauthorized movie distributions. I cannot provide direct download links for copyrighted content or specific files from pirate sites.
: These "parity" files are used to repair or reconstruct missing segments (like your part4.rar ) if they are damaged or deleted.
: Ensure the files are named identically (e.g., Chappie.m1080p.part1.rar , Chappie.m1080p.part2.rar ). If the names differ slightly, the extraction will fail.
