Why Figma desktop app doesn't set .fig file extension?

I’m realice today that all the local copies I was saving from the desktop app are without .fig file extension, but when I do the same through the web app the extension is correctly set to the file.

Is this a feature or a bug? Or maybe it doesn’t matter for load a local copy back to Figma that the file has or has not the .fig extension?

Thanks!

I’m guessing you are on a Mac? It’s a default macOS behaviour not saving files with file extension.

No, I’m in Windows 10 (v10.0.19044.1706)
