Storage method for personal digital devices

Abstract

In a device having data storage, storage space is adaptively controlled by monitoring what pre-stored instructional information is used and how the pre-stored instructional information is used. Some or all of the storage space containing the pre-stored instructional information may be overwritten with user data based on the adaptive control. However, some instructional information may be designated as not overwritable. If access to an external storage device is detected, such as via a communications network to a remote web site, then the pre-stored instructional information can be partially or completely overwritten and instructional information accessed when needed from the external storage device. If additional storage space is still required for user data after all the overwritable pre-stored instructional information has been overwritten, then user data may be transferred to the external storage device for remote storage. The overwriting may be automatic or interactive.
