Struggling to repro this one @rettinghaus - am I missing any repro steps? (see video)

No, but it still doesn't work for me. Weird. I tried (again) different pieces and all result in a .mscz file.

Strange - @zacjansheski can you investigate?

I am getting the same issue on Mac OS14.4
Works as expected with version 4.2
Issue does not occur on Windows 11

I think it comes down to the file name chosen. If you explicitly have MSCZ in the file name, that is what gets written, regardless of the type setting in the dropdown. So on systems where the file dialog automatically changes the file extension when changing the type, the right thing appears to happen by default. But if the extension doesn’t change automatically, and you don’t change it yourself, you end up with an MSCZ file written. At least that is what I think I am seeing on both Linux and Windows.

In the video above, it seems the system is set to hide the extensions, but presumably they are being changed automatically. On my Windows system, the extension is shown, and it does not change with the dropdown, and unless I change or remove it manually, I see the bug. I guess on a Windows system set to hide extensions, it might not occur.

This seems the same on 4.2.1, BTW.

I can support @MarcSabatella's theory. If I type in a completely new name it works. So obviously it's just the hidden file extension that doesn't get updated.

Spot on @MarcSabatella - I changed my system settings to "show all filename extensions" and can repro now.

After doing some digging I discovered this is actually a duplicate of an ancient bug #11615. It looks like some fixes are actually in the pipeline already, I'll chase these up.

Many thanks!
