* 1 For details about using a computer to perform storage memory file and folder operations, see "To
transfer data between the calculator and a computer" (page 10-3).
Meaning
In the MEMORY mode, a level 3
nested storage memory folder is
displayed, and it contains a level
4 nested folder. (The level 4 folder
will be displayed, but it cannot be
opened.)
The calculator memory file system
is corrupted or the storage memory
format is one that cannot be read by
the calculator.
• Use your computer*
files you want to access in the top
three folder nesting levels.
• After reading the information
under "Important!" below, perform
an Initialize All operation as
described in "Reset" (page 9-3).
Important!
Performing an Initialize All operation
will delete all data in calculator
memory, including language data.
If you need the data in calculator
memory, use the USB cable to
connect the calculator to a computer
and copy all of the data you want to
keep to your computer's hard disk*
before performing the Initialize All
operation.
