Blender file error

Hello,
I hope this is the right place to ask this kind of advice!

I’ve been having a problem with the way blender saves my files, and I haven’t been able to resolve it yet, I hope someone will help me solve it.

This is how the files appear to be saved.
Does anyone know why?

The problem probably lies with the way your OS interprets .blend files. If you are using Windows simply change the default application for Blender files.

Apart from that if you have questions about Blender in the future that are not regarding to developement please use Blender Stack Exchange as this website is primarily focused on Blender development.
