Are you speaking English? It looks that way, but I can't parse "you open up solutions". Solutions of/to what? And how does one "open" a solution? I'm also not sure what a "Team Foundation Server" is. I know all of the words separately, but put them together, and they no longer have any meaning for me. I think I missed a trend or a meme or a memo or a brochure or something.

I'm not intending to be a smartass, I really just have no idea what you just said, and looking at the screenshot doesn't really clarify. "Solution Explorer" looks like a file browser, to me.

In Visual Studio parlance, a 'solution' is a set of projects that logically belong together. For example, in a web site, your actual web app may be one project. A back-end scheduling task may be another, etc..

All of these together form a 'solution'. So, in that sense, the term 'Solution Explorer' kinda makes sense if you squint right. Whether or not the word 'solution' is appropriate at all is a different issue entirely...

Ah, OK. So, a "solution" is made up of many projects, which is made up of many files? It sounds very enterprise-y. I'll promise to stay out its way, as long as it stays out of mine.

And I guess I can get by without knowledge of what a Team Foundation Server is or does.
