Hey Igor, ok, thank you for your support! I have contacted the vendor and waiting for a feedback. I think we can close thi issue because it has nothing to do with 7-Zip. Kind regards Rainer

Hey Igor, in the attachment you can find an example Zip-File created by the software. As far as I can check it I can confirm that the ZIP File seem not to be created by 7-Zip. It looks like the software creates the ZIP file directly in the code and not uses some other libraries. I only think that the files are created by 7-Zip, because the software contains 7-Zip exe files from 2010 in the directory of the software. I've contacted the software vendor about this. Best regards Rainer

Hi Igor, thank you for this information. I'm asking because I'm using a backup software that uses 7za with a pretty old version 9.2. The zip file contains 1,5 TB of data. If I now uses the old version (9.2) an test the backup file: Result is "Everything is ok". If I use the 22.01 and test the same file again I got the header errors but the message at the end is "Everything is ok". Regarding to you comment: this is not a problem, correct? I can use the new version to unpack the file and no data is...
