#763 Not all files in the archive are shown & extracted

[Toni Wong]

I receive some zip files from others which PeaZip can not show & extract all the files in the archive properly. The same file can be opened & extracted by other programs without problem such as PowerArchiver and the Windows Explorer.

For the attached zip sample, PeaZip can only show & extract only 1 photo from the archive while PowerArchiver and the Windows Explorer can access all 9 photos without problem.

Please check if there is something wrong.

Thank you for the feedback.

The attached archive is corrupt: PeaZip and 7-Zip detects the error in the data after the first image, and WinRar detects it more specifically in the header of the second image.

While PeaZip and 7-Zip only allows to extract the first image, which contains no error, WinRar (and other apps) allows to extract the entire archive, including the content which contains error(s).

I'll try to improve in future to optionally let extract archives with critical data errors as option, which I understand is very useful for the purpose of data recovery, but it should however be done with caution - image replacing correct files with copies extracted from a corrupted archive, or worse extracting data from archives maliciously modified to hide a payload.
