Download shared link as ZIP sends file with damaged header #8798
Description
Steps to reproduce
- Create a folder and put some files into it
- Share this folder as a link to download
- Open the link in a browser (not macOS) and download the folder as a ZIP archive
- Extract the archive using 7-Zip and the Explorer context menu to extract files to a new folder
Expected behaviour
The ZIP archive can be downloaded and extracted on the client.
Actual behaviour
7-Zip reports an error in the header:
Maybe this is also the reason why ZIP is not used for macOS - not because of a bug in macOS but some problem in the created ZIP file.
