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.
Fig. 2.3.1 Directory Structure
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 "/".
Directory A
Directory An
Directory A2

2.3.1 Directory Name / File Name
Each directory and each file must be allocated a name.
Each directory must be assigned a unique name.
Within a directory or subdirectory the names assigned to the individual files must be unique.
Directory names and filenames are allowed to comprise a maximum of 20 characters; in the case of filenames
these include the characters of the extension (e.g. 17 characters for the name + 3 characters for the extension).
The following characters are not permitted when assigning names:
- Question marks (?)
- Asterisks (*)
- Strokes (/ \)
- Blanks ( )
- Brackets ([ ])
