Memory
There are two types of memory into which you can save data
or install applications: device memory and memory card.
Free memory
To see how much memory is currently in use, how much free
memory remains, and how much memory is consumed by
each data type, select Menu > Options > Memory
details > Phone memory or Memory card .
Tip: To ensure that you have adequate memory,
transfer data regularly to a memory card or computer
or use File manager to delete files you no longer need.
After you install applications to a compatible memory card,
installation files (.sis, .sisx) remain in the device memory. The
files may use large amounts of memory and prevent you from
storing other files. To maintain sufficient memory, use Nokia
PC Suite to back up installation files to a compatible PC, then
use the file manager to remove the installation files from the
device memory. If the .sis file is a message attachment, delete
the message from the Messaging inbox.
Memory card
Select Menu > Tools > Memory .
If you cannot use a memory card in your device, you may have
the wrong type of memory card, the card may not be
formatted for your device, or the card has a corrupted file
