If no files exist, only <mem_used>,<mem_free> is returned.
Because the counter uses a small amount of space in the flash file system for internal
use, the <mem_used> value will not be zero even if no user files exist on the drive.
Examples
The following example returns a list of all files in the folder MyData on the front panel USB storage device.
MMEM:CAT? "USB:\MyData"
Typical Response: +1000000000,+327168572,"-
