I can no longer open downloaded JPEGs

Hi,
I hope someone here can help me. I’m completely confused right now.

I was just trying to download a JPEG from my Nextcloud. I had been able to view this image in Nextcloud earlier, and viewing it in full screen wasn’t a problem either.

But after downloading it, I couldn’t open the image. None of the image viewers I have will open the file.

I then downloaded the images directly using WinSCP, with the same result.

What puzzles me is that Nextcloud shows a size of 4.6 MB, while Windows shows a size of 6.19 MB.

After that, I checked other images as well, and it seems to be the same for all of them.

Some other documents also seem to be affected. In some cases, I can’t open them at all anymore.

What can I do?

I would really appreciate any help.

I’m not sure what kind of data or logs to provide. It’s a strange problem.

Best regards,
BOSSJoe
