There is no computer file, which is immune to corruption. Same is the case with a zip file. It gets corrupted due to so many reasons but one main reason is its large size. Large sized zip files are more prone to corruption. And once a zip file gets corrupted, file extraction fails and your data comes under threat of loss. However, you can restore your data from a valid backup file. But, if you have not maintained a backup or if the backup fails to restore the data, then the only way to resolve the issue is to use a third-party file repair software to
repair zip file.
Suppose, you have a decent sized zip file and you are trying to add more data into it. While you are doing that , an error message appears that states:
End of extra data.
After this error pops up, file extraction seems problematic and in severe cases file extraction becomes impossible and you may not be able to access your precious data stored in the zip file.
Cause:
This issue is frequently observed in large sized zip files. It happens because the maximum size limit of a zip file is 4GB and if this size limit is exceeded, the file becomes prone to corruption. This further leads to failure of the extraction process and inaccessibility of your precious data.
Resolution:
Due to the non-availability of an inbuilt tool or feature that can recover the contents of the zip file in WinZip, there is no such solution to this problem. Therefore, you need to apply some other methods to resolve the issue. In such a situation, try using a
zip repair software that can scan and repair the corrupted or damaged zip file quickly and completely. The repair software extract data from the corrupt file using complex algorithms. In addition, the zip repair software store the recovered content (original content and settings) in a new file without making any changes or alterations to the original file.
