A path, the general form of the name of a file or directory, specifies a unique location in a file system. A path points to a file system location by following the directory tree hierarchy expressed in a string of characters in which path components, separated by a delimiting character, represent each directory. The delimiting character is most commonly the slash ("/"), the backslash character ("\"), or colon (":"), though some operating systems may use a different delimiter. Paths are used extensively in computer science to represent the directory/file relationships common in modern operating systems, and are essential in the construction of Uniform Resource Locators (URLs).
Systems can use either absolute or relative paths. A full path or absolute path is a path that points to the same location on one file system regardless of the present working directory or combined paths. It is usually written in reference to a root directory.
A relative path is a path relative to the working directory of the user or application, so the full absolute path will not have to be given.
