[BUG] Problem with images and audio rendering when extracting and recompressing the export zip file

[DkAngelito]

Hi,
I have a zip file with the exported chat and everything works fine with this original file. The images and audio files are displayed correctly. But if I extract it and recompress it without modifying anything (using the zip menu under File Explorer in Windows 11) and try to process the new zip file, the images and audio files are not displayed correctly.

Recompressed Zip File

The tool relies on the format that is created by the export functionality of the WhatsApp mobile app. Why unzip and rezip the content? If for any reason you want to remove something from the zip file, edit it directly (instead of unzipping and rezipping it). Use TotalCommander, which is free and should modify zip content properly.
