: If the extraction fails, check the file sizes of all 82 parts. They should all be roughly the same size, except for the very last one. A 1kb file is often a sign of a failed download.
To access the content, you must join these parts back together by extracting them as a single unit.
Do you have downloaded, or are you missing a specific part?
Note : You only need to open the file. The software will automatically find and join the remaining 81 parts for you.
