I want access to every file and folder on my network from any comp

I have a home network using a router that is both a switch and wireless. I
want to be able to access any folder or file from any computer on the network
without having to go through all of the hassle of the the new security puts
me through. I don't have a need for the complicated security a large
installation with many users needs. I own everything and want access to
everything from any computer at any time.

How do I get this kind of access in a simple way. In order to get access to
an external drive on one of my computers I had to spend about an hour and a
half trying to figure out what else I needed to do. I'm getting really tired
of getting messages that I don't have permission for that, all of the time.

Every new operating system Microsoft has come out with has made computers
harder to use. What happened to "User Friendly?"

Sincerely,
