2.3 Directories / Files
Related files are grouped and stored in
directories
. These directories can also contain other directories, so-
called
subdirectories
, which, in turn, contain files and other subdirectories.

Each file is identified by its
path
which specifies its exact position within the directory structure in the following
form:
Example: /DirA/DirA1/DirA2/File.xx
The individual directories and files are separated by a stroke "/".
