A system and method for updating electronic files and file components are provided. An upgrade client of a remote device receives a delta file block that codes differences between an original and a new version of a file. The upgrade client stores the delta file block in a first memory area. The upgrade client writes an original file block corresponding to the delta file block from an original memory area to a second memory area. A file updating algorithm generates an updated file block in the host device using the received delta file block and the original file block. This updated file block corresponds to the original file block, and is stored in a third memory area. The upgrade client updates the original file block of the remote device by writing the updated file block over the original file block in the original memory area of the remote device.
