Many households now have more than one computer. More people are buying a laptop to go with family desktop. Add a router and you have a network. Once you have a network, there is no reason to use “Sneakernet” to move your files from one computer to another.
Turn on File Sharing. This will let you get to files on Computer 1 from Computer 2.
Depending on your needs, you can control the access of network users to resources that are shared. The control falls into two general categories and is “set” by the computer doing the sharing.
Read
Read & Write
Read access permits a network user to open a file for viewing, but the network user cannot change or delete the file. If the network user has Read and Write access, the network user can view, change and even delete the file.
I share all my music and photos over the home network in Read mode. I don’t want someone accidentally deleting something. If a network user wants to modify a photo, that photo can be copied to a computer where the copy can be changed, but the original is unaltered.
Sharing files on your home network does not share them with people on the Internet if you have a router/firewall. Someone would have to break into your home network to get to your shared files. An added layer of protection is to require a valid username/password for network users to access files that are shared. In this way, a user not only has to be on the network, but also has to know a working username and password on the computer sharing the files.
Behind a firewall, your shared files are pretty safe from the Internet.
