摘要

Exemplary embodiments provide access to updated files performed by a computer including at least one processor. In response to an application receiving an update containing the transformed content of the old file, a new file is created with the transformed content copied while access to the old file is maintained, and logical block addresses (LBAs) of the old file are created. addresses) are mapped to physical block addresses (PBAs) of the old file, and the logical block addresses of the new file are mapped to the physical block addresses of the new file. The method described above includes automatically swapping the mapping of the old file logical block address from the physical block address of the old file to the physical block address of the new file; removing the mapping of the logical block address of the previous file to the physical block address of the previous file; and controlling the mapping of the logical block address of the new file and the physical block address of the new file.
