what is the rule to name new project or scene?

Ecah time I try tocreate a new project , as I am learning unity, I cannot save under any name I choose
and it forces me to save somewhere I do not want???
what is wrong with this?

For example? I’m curious what these forced names are.

I create a new project
I want to save it in a folder where I want to keep all unity projects together
I try to do "save scene as " but it places me in a folder other than the one I had created. If I enter a any name at that level, it refuse to accept it, or I miss something here, and I have exit save as, then redo it and keep the location where unity is placing me, which is somewhere in Assets from another project, and I don’t see why that should be?
Also the name I want the project to be saved as is not accepted
Whatt is going on here?
For the other projects I have end up enteringt any thing like aaqsefearefa and that worked but all the new test projects I did are scatered in other projects that I downloaded from the web for learning??

Scenes and projects are totally different things. You can only save a scene inside the project it belongs to.

You can’t name a project the exact same thing as an already existing project (for obvious reasons), but there are no other limitations I’ve ever encountered.
