Setting Up Shared Folders and Permissions
To allow remote access of your resources, you must make them available on the network to other users on other computers. Making some resources available on the network does not mean that you have to make all resources available on the network. Windows NT enables you to selectively choose which folders you want to allow access to and which you want to remain private to that workstation.
To share a folder in Windows NT means to make that folder available to other users on the network. If you have a resource that you want others to access, you must choose to share that resource. Sharing can only be done at the folder or directory level—it cannot be done at the individual file level. Thus if you want to share only one file, you must create a folder and put just that one file into the folder. After you put the file in the folder, you then need to share that folder. After a folder is shared, users with rights to that shared folder have access to all the files and subfolders beneath it as well.
