This section explains how to connect the calculator to the computer and open the calculator

u Main Memory Data during a USB Connection
The contents of the @MainMem folder in the calculator drive correspond to the contents of the
calculator’s main memory. Each time you establish a connection between the calculator and a
computer, the contents of the calculator’s main memory are copied to storage memory.
If there is not enough storage memory capacity to support the copy operation, the message
“Storage Memory Full” will be displayed on the calculator and the copy operation will not be
performed. If this happens, delete files you no longer need from storage memory to increase
capacity, and then try establishing a USB connection again.
Each group in main memory is displayed as a folder in the @MainMem folder. Also, each data
item in main memory is displayed as a file in the @MainMem folder.
Main Memory group names and data item names are displayed in the @MainMem folder as
shown in the table below.
