File Naming
Conventions
The file system is a flat file system which means directories are not
supported. Files are uniquely identified by a file name in the following
format:
filename.ext
where:
❑ filename is a descriptive name for the file, and may be one to
sixteen characters in length. Valid characters are lowercase letters
(a–z), uppercase letters (A–Z), digits (0–9), and the following
characters: ~ ’ @ # $ % ^ & ( ) _ - { }. Invalid characters are: ! * + = “|
\ [ ] ; : ? / , < >.
❑ ext is a file name extension of three characters in length, preceded
by a period (.). The extension is used by the switch to determine
the file type.
The following is an example of a valid file name for a configuration file:
standardconfig.cfg
The following is an example of an invalid file name:
sys/head_o.cfg
The backslash character (/ ) is not a valid character because
subdirectories are not supported.
Using Wildcards to Specify Groups of Files
You can use the asterisk character (*) as a wildcard character in some
fields to identify groups of files. In addition, a wildcard can be combined
with other characters. The following are examples of valid wildcard
expressions:
*.cfg
*.key
28*.cfg
