ABSTRACT:
A computer is disclosed having a semiconductor memory; a disk data storage device of the type which automatically switches to a low power consumption mode when disk access is not required; and means for associating an application program with a plurality of data files which are usable by the application. The computer is arranged to load the plurality of data files from the disk data storage device into the semiconductor memory before use of the application and to save at least any modified ones of the plurality of files back to the disk data storage device after use of the application. In this way, access to the disk data storage device is not required during use of the application program, thereby reducing power consumption of the device.
