Something About Folder Sharing
In organizations or home setups where there are multiple computers connected to each other, in order to transfer files from one computer to another administrators use to share the folders on one computer (generally known as file server) and make them accessible from all other computers in the network. In order to do so administrators normally configure and set NTFS and share permissions on the shared folders which, as a result, help them control the accessibility of user accounts or groups on them.
By default Windows operating systems allow only administrators to share folders of the computers. While doing so, they can set share permissions on the shared folders which are by default set as Read for Everyone group. Other two share permissions that administrators can set on shared folders are Full Control and Change.
Default share permissions set on any shared folder are because of security reasons however Microsoft recommends that in production environments administrators must set share permissions as Full Control for Everyone group and then they must set NTFS permissions on the shared folders to control and limit their accessibility granularly.
Other Shared Objects
Windows administrators can share not only folders but they can also share other objects such as printers, optical media drives, removable storage devices, volumes (hard disk drive partitions), etc. According to the type of object that administrators share for remote accessibility, the options for share and NTFS permissions vary. For example, when a printer is shared the print permissions that administrators can set may include Print for Everyone group, Manage Documents for Creator Owner group, etc.
Irrespective of the objects that administrators share on a Windows operating system, in the background Server Message Block (SMB) runs, which is an application layer protocol that helps in transferring information from a shared location to the requesting remote computers.
Share names are the alias names for the shared folders by which the shared folders can be identified by the users when they are accessed from remote computers. When administrators share a folder, by default the actual name of the folder becomes its share name however for security reasons administrators can rename the shared name of the folder in order to hide its actual name from the users. For example, if a folder’s name on a local computer is ABC, when an administrator shares the folder by default its shared name remains ABC but Windows allows administrator to rename its shared name to XYZ (or any other name as desired). When users log on locally to the computer the folder name that they would see would be ABC but when the computer is accessed from the network the name of the folder displayed to the users would be XYZ. A folder, when shared, can have multiple share names and each share name can be assigned with separate sets of permissions.
Sharing the Folder

- Once located right-click on the folder and from the context menu click Properties.
- From the opened properties box go to Share tab and click Advanced Sharing.
- On Advanced Sharing box check Share this folder checkbox and click OK to share the folder with default permissions. Optionally, name in Share name field can be renamed to change the default shared name and Permissions button can be clicked to change the default share permissions before clicking OK.
- Back on folder properties box click Close to close the box.
