Often the question arises why the file should be split into several parts so as to form a file part1, part2, part3 and so on. This is done because some servers for limiting the maximum size allowed in a single upload.
For example, a server only allows one file upload maximum 100MB. Though we will upload the file size reaches 450MB, what to do? Direct upload files of 450MB is, clearly impossible. The only way is to split the file up to 100MB / file, that file will be split into 5 parts to be uploaded on the server. It will form part 5 file is part1, part2, part3, part4 and part5.
In the last part file usually has a size smaller than the size of the file before the same. Example: Suppose the file there are 5 pieces of each:
part1 = 100 MB
part2 = 100 MB
part3 = 100 MB
part4 = 100 MB
part5 = 50 MB
Keep in mind, part1 to part4 size must be equal, if not as large as it stands to reason the file with a different size (usually smaller) is part of a corrupt file.
Keep in mind also that prior to extraction file, make sure the file name on the back. Rar has all the same. If there is a different file name then it can cause failure of the extraction process.
Only then do the extraction. Extraction can be done with winrar or 7zip application.
The way is very easy to extract. Do extract one file then automatically file the other part will come processed
If the above are not available, try to time the extract with winrar, checklist Keep Broken Files section as shown below:
But remember this way because even if the file is corrupt force will still be extracted, so that if a large corrupt then the result is also not optimal.
