After you install applications to a compatible memory card,
installation files (.sis) 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.
