Abstract
The present invention is intended to download software more securely to update the functions of software. When files are downloaded from a server into an information processing apparatus, a CPU downloads the files into bank A or bank B of a storage unit and copies the files into bank C. The CPU calculates a checksum of each file and a total checksum of all files and stores the obtained checksums into a memory. The checksums stored in the memory are compared with those of the server. Any file that has an error is downloaded again. In addition, at the end of the operation of the information processing apparatus, a normal end flag is stored in the memory. If, at the next startup of the information processing apparatus, its last operation is found to have been abnormally ended, the apparatus is started up by use of bank C. The present invention is applicable to personal computers.
