Windows 10: documents vs mydocuments and publicdocuments What? Why? How? When?

I'm wanting to learn some history and fill in some gaps in my general knowledge and experiences using Window over the years.
I would like to know all about what those Mydocuments, Mypictures, My[etc] folders are for. What are they? Why did they suddenly appear way back when Windows was young? What extensions of the concept are there besides Publicdocuments, etc.? Will new ones be created in future versions of Window 10?
Not knowing the answers, I have never looked into the issue of taking advantage of them to do anything. Early on, my interest in them all but disappeared when I tried to investigate them on my PC only to find that I had no permissions to access them. My conclusions were: 1) the system must need them for something, but I sure don't; and 2) it will be really interesting to learn what they are all about if their names say they are mine, but I have no permissions to them on my own system without making changes to the way the system created them from nowhere without my explicit "permission".
Now that I am a really old guy with a lot of time on my hands, and have never been aware of any problems caused by my ignorance of them, my curiosity about them is greater than ever.
This is all very low priority. I still don't know of why I may ever need to use them. Sharing other public folder files locally and on my LAN has never been an issue for me.
My apologies for such a long post for a simple question. I did lots of searches before posting, but with no success. If there is a better place where this thread should be moved, that's ok with me.
I'll be grateful for any info I can get to help me educate myself.
Thanks,

Document names uploaded via web interface are auto prepended with "MyDocuments"

On my wife and my phones when uploading a document via the web interface, it will prepend "Mydocuments" to the file name.

Example.

Baby-names.pdf gets changed to MydocumentsBaby-names.pdf

and is put at the root of the phones internal storage instead of in "My Documents"

Creating a Mobile Word document does not put the file in a location that the My Phone sync service auto sync's. Might be a good idea if it did.

Loving the service though

Thanks for all your hard work MS

Windows 10 Access Denied - Documents and Settings

Using a Dell PC and a Toshiba laptop.

Wireless in-home network.

Changed from Windows 7 to Windows 10.

If I try to open the files G B-P suggests above--C:\Users\Owner\documents, or using my name instead of 'Owner'--access to Documents files (not MyDocuments) is NOT allowed.

I have gone through the steps for sharing and adding permissions, but as Administrator and Owner, as I certainly am, I cannot access files that I created myself.
