FILESystem:FORMat (No Query Form )
Formats a mass storage device. This command should be used with extreme
caution as it causes all data on the specified mass storage device to be lost.
Drive letters (e.g., E:) are case sensitive and must be upper case. For all other
FILESYSTEM commands, drives letters are not case sensitive. Example:
FILES:FORMAT "E:/" Formats the USB flash drive installed in the oscilloscope's
front panel USB port.

FILESystem:LDIR? (Query Only)
Returns a semicolon separated list of every file and directory in the folder

type, and modification date/time. Each entry is a semicolon separated list:
<file name>;<type DIR or FILE>;<size in bytes>;<date>;<time>

Arguments
<directory path> is a quoted string that specifies the directory to create
Examples
FILESYSTEM:MKDIR "E:/NewDirectory" creates the directory named
NewDirectory at the root of the D drive.
These two commands create the directory MyNewSubDirectory within the
existing directory MyDirectory at the root of the D drive:
FILESYSTEM:CWD "E:/MyDirectory"; F ILESYSTEM:MKDIR
"MyNewSubDirectory"
This, of course, assumes that E:/MyDirectory already existed and was not a
read-only directory.
