:MMEMory Commands
:MMEMory commands are used to set and query the related information of the
internal and external memory. The internal memory ("INT:\") of the instrument is
always present while the external memory ("USB:\") is available only when the rear-
panel USB HOST interface detects the USB storage device.
Many :MMEMory commands refer to folders and files. These folders and files have
specific structures, described below.
•
Absolute paths begin with "/" or "\" and start at the driver identifier (INT or USB).
•
Folder and file names cannot contain the following characters: \ / : * ? " < > |,
and cannot start with ".".
•
Relative paths begin with ".\" or "./" and level down from the current path.
•
Going back to the parent path begins with "../" or "..\" and levels up from the
current path.
•
The combination of folder and file name cannot exceed 200 characters.
