In a network, the Universal Naming Convention (UNC) is a way to identify a shared file in a computer without having to specify (or know) the storage device it is on. The UNC can be used instead of the local naming system (such as the DOS naming system in Windows). In Windows operating systems, the UNC name format is:

\\servername\sharename\path\filename

universal naming convention (UNC)

A naming convention for files that provides a machine-independent means of locating the file. A UNC name will usually include a reference to a shared folder and file accessible over a network rather than a folder and file specified by a drive letter and path. For example, the UNC name for a database named Northwind.mdb on a shared directory named Samples on a computer called MyWorkstation would be \\MyWorkstation\Samples\Northwind.mdb.

The UNC is particularly useful in Web-based applications because it allows you to reference data that is not necessarily stored on a particular Web server.
