How find outlook.pst and archive.pst in Windows Explorer ?

we just got a new PC with WIndows 7

I'm trying to point my backup program to where my outlook.pst and archive.pst files are located, but they are not visible when I go down the tree.

when I do a search in Explorer, it locates the file as being located in C:/Users/MyPC/AppData/Local/Microsoft/Outlook
but when I go to look for it, there is not folder called "AppData" in the location C:/Users/MyPC/

where can I find the files I'm looking for ?
