UNC Name Syntax
UNC names identify network resources using a specific notation. UNC names consist of three parts - a server name, a share name, and an optional file path. These three elements are combined using backslashes as follows:
- \serversharefile_path
The share portion of a UNC name references a label created by an administrator or, in some cases, within the operating system. In most versions of Microsoft Windows, for example, the built-in share nameadmin$ refers to the root directory of the operating system installation (usually C:WINNT or C:WINDOWS).
The file path portion of a UNC name references the local subdirectories beneath the share point.
Or to be more exact, you can understand it this way:
\servernamesharenamepathfilename
UNC Name Examples
Consider a standard Windows XP computer named teela. In addition to the built-in admin$ share, say you have also defined a share point called temp that is located at C: emp. Using UNC names, you would connect to folders on teela as follows:- \teelaadmin$ (to reach C:WINNT)
- \teelaadmin$system32 (to reach C:WINNTsystem32)
- \teela emp (to reach C: emp)
