Today, there is no reason not to share files. Sharing files allows pictures, music and any form of data to be shared among users in a home. A well-organized home network can share a folder on their Microsoft Window's Vista Computer and drop all of their pictures and documents into this folder allowing all of the users to share this information.
In order to share a folder, double click Computer and then double click your hard drive. Right click, point to New and create a new folder named Shared Files (or whatever you want). Right click the folder and select Share. Select the user you want to share the folder with. You can then assign rights to each individual. The permissions are reader, contributor and co-owner. A reader can only view files, a contributor can view and change files and a co-owner can do anything with the files.
Once you select the permissions, click Done and the UNC (Universal Naming Convention) path to get to the files from another computer will be displayed.
At the guest computer, type \\thecomputername\thesharedfilename and you should see the files you are sharing.
