Why Isn't The AppData Folder Visible. What the H Does M$ Have to Hide

I try to open a video on my phone and Windows 7 copies it to some obscure folder. Fortunately, the search tool is working okay, and searching for it, shows that the file is in

C:\Users\Jul\AppData\Local\Temp\WPDNSE\{000076DD-0001-0002-0000-000000000000}

So, why the H does the crappy software OS designers at M$ do something like this? Is this folder going to be purged someday? When?

And why is it not pos to see the AppData folder when you go to Users\Jul?
