SD folders are DOS folder, not calculator directories. Use the silver
left arrow to browse into the folder. You can't recall or store them.
Copy an HP directory to the SD card and you will see the difference.

You can also do that for subdirectory contents as well.  See here,
second PDF.

> The card is a 256MB card formatted as FAT32.

Reformat it on the calculator, or on the PC using FAT16. Otherwise
there is a long wait time every time you power on the calc due to the
long time it takes to scan so many clusters with FAT32.

Type VERSION and you should see the version number. If it is not 2.09,
use this one:

If you want to be able to create folders, delete folder, move stuff,
copy stuff, etc on the card, use this:
