File Naming Conventions
To enable files to be used in different file systems, consider the following file naming
conventions:
●
The
filename
can be of any length and
is case-sensitive
, i.e it is distinguished
between uppercase and lowercase letters.
●
All letters and numbers are permitted (numbers are, however, not permitted at the
beginning of the filename).
●
Avoid using special characters.
●
Do not use slashes "\" and "/". These symbols are used in file paths.
●
Avoid using the following filenames:
CLOCK$
,
CON
,
COM1 to COM4
,
LPT1 to LPT3
,
NUL
or
PRN
They are reserved by the operating system.
Wildcards
The two characters "*" and "?" function as "wildcards", i.e. they are used for selecting
several files. The "?" character represents exactly one character, while the "*" charac-
ter represents all characters up to the end of the filename. "*.*" therefore represents all
files in a directory.
Filename and file path
When used in remote control commands, the parameter
<filename>
is specified as a
string parameter with quotation marks. It can contain either the complete path including
the root user directory
/var/user
and filename, or only the filename. The filename
must include the file extension. The same applies for the directory
/var/volatile
and for the parameters
<directory_name>
and
<path>
.
Depending on how much information is provided, the values specified in the parameter
or with the command
MMEM:CDIR
are used for the path and drive setting in the com-
mands.
