Saved incomplete attachments from bigger emails

Federico Fanton replied
Federico Fanton

Hello, I've just received an email with two attachments: a 28kB PNG and a 18MB ZIP. I can double-click and show the image normally, but when I do the same on the ZIP, I get a "is not an archive" error. If I try to save the attachments on the desktop, the PNG gets saved normally, while the ZIP shows up as a 27-bytes file.

I'm using Thunderbird 102.9.0 (64-bit) on Linux. If it's relevant, under "Synchronization & storage -> Disk space" I have "Syncronize all messages locally regardless of age".

Thanks for your help!

First, I have no 'fix', but you might want to check from your online account to view the zip file, as it is not uncommon to receive large zip files that are corrupted.

Sorry, I forgot to add that if I save the email itself to the desktop and then open it in Thunderbird, I can open the ZIP file correctly.
