Path in computer file systems is in general the human-readable address of a filename or directory specifying a unique location in a file system, and expressed by a string of path components separated by a delimiter (most commonly the slash "/" or the backslash "\"). PATH (variable), is an environment variable specifying a list of directories where executable programs are located.
