If you have two or more PCs linked together in a network, then you can share files between users. Sometimes only one user will use a file at any particular time, in other cases several users might be looking at a file at the same time. In these cases, the network software needs to be able to allow more than one user to access the same file. To do this there is a special file attribute bit called Shareable. When this is set to 1, the file can be shared by more than one user. To set a file attribute bit use the Attrib command from DOS or display the file's Properties window. If you are not connected to a network, you don't need to worry about file sharing.
