Alternative Descriptions
(Universal Naming Convention) A standard for identifying servers, printers and other resources in a network, which originated in the Unix community. A UNC path uses double slashes or backslashes to precede the name of the computer. The path (disk and directories) within the computer are separated with a single slash or backslash, as in the following examples. Note that in the DOS/Windows example, drive letters (c:, d:, etc.) are not used in UNC names.
//servername/path Unix
