File Naming
Conventions
The file subsystem provides 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 which is three characters in length.
Valid characters are lowercase letters (a–z), uppercase letters (A–
Z), digits (0–9) and the hyphen character (-). The extension is used
by the switch to determine the data type of the file and how to use
the file. Each file name extension must be separated from the
filename portion by a period (.)
Note
The certificate file, certificate enrollment request file, and key file
types are only appears in the AT-S60 version 2.0.0 software.
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 delimiter character and
directories are not supported.
