Mass storage location
Without any additional measures, the R&S
SMM100A stores user files on the internal
memory or if connected, on a memory stick.
Both, the user directory
/var/user/
on the internal memory or the
/usb/
directory
on the memory stick, can be used to
preserve
user-defined data. Any directory struc-
ture can be created.
The
/var/volatile
directory serves as a RAM drive and can be used to protect
sensitive information. The data is available
temporarily
.
Default storage location
The R&S
SMM100A stores user data in the user directory.
In the file system, user directory is always indicated as
/var/user/
.
In manual control, you access this directory via the "File Manager", see
on page 503. In remote control, you can query it with the

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.
File extension
The file and the optional file
extension
are separated by a period sign. The
R&S
SMM100A distinguishes the files according to their extensions; each type of file is
assigned a specific file content and hence a specific file extension. Refer to
ter A.2, "Extensions for user files"
on page 1035 for an overview of the supported file
extensions.
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-
