Path (computing)#Uniform Naming Convention

Uniform Naming Convention (also universal naming convention, short- UNC) is widely used as a standard for the names of addresses of shared resources in a computer network. The UNC address represents a network path via which you can address and use resources of other computers on the network. These resources can be directories (also called folders or file folder ) or entire disks for which previously must be a network share so that the access to the data from other computers is possible. Due to the direct use of a UNC address connecting eliminated with a network drive, which you can use for example for permanent data sharing in a home or office network. In some cases it may be useful also to access local data located on a UNC path.

Syntax

Windows

Network resources

The format of such a network path on Windows is:

\ \ Server \ sharename \ path or

\ \ IP address \ sharename \ path This is the server name always the name of the computer use, on which the data resides. This calculator provides the data available, it acts as a server. The computer name can be found:

  • Hostname with the command or ipconfig / all at the point hostname
  • About the system features: for example, right-click My Computer → Properties or in the Control Panel → System

If the IP address is an IPv6 address, the notation must be changed because of not allowed colons:

Instead of

\ \ 2001: db8 :: babe: face: cafe: dead \ sharename \ path so

\ \ 2001 - db8 - babe -face -cafe- dead.ipv6 - literal.net \ sharename \ path The square brackets normally used in such cases will not work here.

The share name is the name under which the resource has been released, such as a folder name or a drive name.

The path is the directory path in which, for example, the file is stored on the resource.

Local Resources

The format for local paths on Windows, ie data that are available on the used computer itself is:

\ \ \ C: \ data or \ \ \ C:. \ Data This variant also increases the maximum path length of 255 characters to 32,767 characters.

Linux / Unix / Mac OS X

The input format in Linux / Unix / Mac OS X is:

/ / Servername / sharename / path or

/ / IP-Adresse/Freigabename/Pfad Multiple UNC Provider

With the Multiple UNC Provider ( MUP) ​​, other network resources can be achieved in addition to the usual SMB network shares. While support for DFS was already installed in older versions of Windows can use a Windows Vista default installation, a WebDAV drive on the syntax

\ \ Server name \ DavWWWRoot \ path be achieved. The syntax used in earlier versions of Windows

Http://Servername/Pfad but also works with Windows Vista, for example, when mapping a network drive. A secured via SSL connection is with the syntax

\ \ Server name @ SSL \ DavWWWRoot \ path reachable. The syntax was here earlier

Https://Servername/Pfad see also
