It's a directory path. Paths are often expressed by listing the directories along the path separated by slashes. For instance, animals/prehistoric/dinosaurs would represent the path starting at the directory named animals, passing through its subdirectory named prehistoric, and terminating in the sub-subdirectory dinosaurs.
A directory within an existing directory is called a sub directory.
Mkdir command creates a subdirectory under a directory (MD creates a directory) . The command Chdir changes the current Default directory(CD changes the current directory). The Rmdir removes the subdirectory(RD removes a directory).
That is a subdirectory (or subfolder) of the Windows (Or WinNT) directory which contains very important parts of the Windows operating system.
1. The most straightforward way to create a create a subdirectory in the current directory is mkdir name where name is the name of the new directory. 2. Another way is to move a directory and its descendants from somewhere else: mv path name where path is an absolute or relative pathname for an existing directory hierarchy, and name is the directory name it will be given in the current directory. 3. Various utilities for unpacking archives may create directories as they execute; for example cpio, tar, unzip etc.
It is the path as relative to the topmost directory, /. For example, /usr/bin is absolute, but ../bin is relative (Means "the directory 'bin' in the parent of the current directory.")
