Describe the bug I can add files from Windows Explorer to attachments via drag & drop. This also works if I have an open zip file in explorer and drag and drop the files. But the files seem not to be unzipped in the process. Instead, there is now a 0 B attachment that cannot be opened.

To Reproduce Steps to reproduce the behavior:

1. Create a ZIP file with files inside.
2. Open the ZIP file in Windows Explorer.
3. Drag and drop a file from the ZIP file to the "Upload attachment" area in Nextcloud
4. There is no a 0 B attachment that cannot be opened

Expected behavior Either the file is decompressed and then uploaded correctly, or the drag & drop should not work.

The screenshots are not ideal because I used a file that actually has a file size of 0B (empty txt file) but this also happens with larger files.

I don't have a windows machine reachable right now, but could you check if uploading by dragging from an archive works fine within the files app?

The files app silently ignores the drag & drop from an archive.
