Abstract: When a repair problem exists in a case of a fully loaded partition, or when a feature of a terminal device needs to be expanded but there is no remaining space in a related partition, the terminal device may search for and download a patch file from a server, and a compressed empty device (loop) is used to expand the feature. In some conditions, the empty loop device and the fully loaded partition may be combined to form a new device. In some other conditions, based on a packaging technology in a disk block dimension, a changed file is repackaged in the disk block dimension.
