How do you explain the following, and what can I do about it? I can find a file using the following command: %localappdata%\Microsoft\Outlook\ which does show me the path I need.
…but! When I try to follow this very same path using “My Computer”, a subfolder in the path doesn’t appear! What the heck is going on here, and what’s the solution? Note: I have Win 10 Pro.
The %localappdata% part is just a variable for a big chunk of the path so it can get to the final folders without having to know who you are. On my PC, the actual path to %localappdata%\Microsoft\Outlook\ is c:\users[my user id]\AppData\Local\Microsoft\Outlook. So, the %localappdate% is essentially the same as c:\users[my user id]\AppData\Local.
In Win10, if you click on Start and just start typing the name of the file or folder you want to find, it’ll start searching for it. Does that work for you?
It’s probably a hidden folder.
“My Computer” is the ultimate root of your machine. AFAIK, the only ‘path’ that might apply would be the actual name (network name) of the machine.
Read this to find out how to show hidden files and folders:
C:\Users[UserName]\AppData is a hidden folder. Use the instructions already given to show it.
SD saves the day again! I figured it was a hidden folder, and I was trying to “unhide” it using the older way from older versions of Windows (under “Properties”). When I did this, it appeared as if there were nothing to “unhide”. With Win 10, I am still not quite accustomed to everything in the ribbon bar at the top. I would have never found where to check the box to show hidden files. Who knew Microsoft actually made this so simple? Oh, that’s right…you all did! 
The rule of thumb with any feature in Windows or MS Office is - If it is particularly useful or necessary the feature will either be hidden or deleted in the next version.
