Abstract: A file system 130 has a function of integrally managing a first recording region 9a in a first auxiliary storage device and a second recording region 9b in a second auxiliary storage device. A reception section 110 receives information indicating the type of the file to be recorded. A place information acquisition section 114 acquires information regarding a recording place corresponding to the received information indicating the type of the file. A metadata processing section 134 defines metadata regarding a recording place of the file in reference to the acquired information regarding the recording place. A recording processing section 132 records the file into the first recording region 9a and/or the second recording region 9b according to the defined metadata.

Abstract: A first correspondence table indicates a correspondence relation between logical blocks of a first file and physical blocks of a physical storage. A second correspondence table indicates a correspondence relation between logical blocks of a second file and the logical blocks of the first file. An access request receiving section receives an access request for the second file. A block conversion section refers to the second correspondence table, identifies a logical block of the first file associated with the logical block of the second file that is subject to the access request, and then refers to the first correspondence table to identify a physical block of the physical storage associated with the identified logical block of the first file. An accessing section accesses the identified physical block.

Abstract: An output processing unit 112 generates image data of a game being played by a user. A ring buffer 118 records the image data generated by the output processing unit 112. A file generation unit 124 generates a map file which is used to reproduce the image data recorded on the ring buffer 118 in the order in which the image data has been recorded on the ring buffer 118, and then records the map file on a file recording unit 126.

Abstract: Before a file logically divided into a plurality of groups is downloaded, an acquisition section acquires meta information set for the groups. An area management section reserves recording areas in a first storage and a second storage according to the meta information of the groups. A recording processing section records the groups into the first storage or the second storage according to the meta information of the groups.

Abstract: An attribute information setting section loads information indicating whether or not access to each of a plurality of files is allowed, into a memory. A readout request receiving section receives a readout request including a file path from a program. A hash value deriving section derives a hash value of a file path included in the readout request. A file confirming section confirms whether or not the derived hash value matches with one of hash values of the files included in software. A determining section refers to the information loaded into the memory by the attribute information setting section in a case in which matching of the hash values is confirmed, to thereby determine whether or not a process on the file which has been subjected to the readout request is executable.

Abstract: A first correspondence table indicates a correspondence relation between logical blocks of a first file and physical blocks of a physical storage. A second correspondence table indicates a correspondence relation between logical blocks of a second file and the logical blocks of the first file. An access request receiving section receives an access request for the second file. A block conversion section refers to the second correspondence table, identifies a logical block of the first file associated with the logical block of the second file that is subject to the access request, and then refers to the first correspondence table to identify a physical block of the physical storage associated with the identified logical block of the first file. An accessing section accesses the identified physical block.

Abstract: A server includes a processor to: generate vehicle condition information for one or more target vehicles to be subjected to data collection based on any condition; and output control command information for causing a matching vehicle that matches the vehicle condition information among the one or more target vehicles to execute predetermined processing.

Abstract: A block processing section divides a file generated by an application into a plurality of data blocks and stored the data blocks in an auxiliary storage device. A metadata processing section stores, in the auxiliary storage device, first metadata including a hash value and information for identifying a storage location of each of the plurality of data blocks. When the file is updated, the block processing section stores an updated data block in another storage location. The metadata processing section stores, in the auxiliary storage device, second metadata including a hash value and information for identifying a storage location of each of a plurality of data blocks including the updated data block. A metadata switching section sets the second metadata to be used for file access.

Abstract: A game machine for development is connected to a host computer, reads out a file requested by a game program under development from a storage device, and executes the game program. In the game machine for development, a file confirmation section confirms whether or not the file requested by the game program is stored in the storage device, a file request section requests the host computer to transmit the file in a case where the file is not stored, and a storage processor acquires the file from the host computer and stores the file in the storage device.

Abstract: A media drive is loaded with a ROM medium on which a plurality of files constituting an application are recorded. A readout block reads out data from the media drive. A memory temporarily stores the read-out data. A providing block provides the data stored in the memory to game software. A recording processing block records the data stored in the memory in an auxiliary storage device.

Abstract: An information processing device processes game data including a startup file and a program file, the game data being formed by adding, to an image file of game data including a plurality of files that are each assigned one or a plurality of blocks and including metadata of each file, metadata including a signature attached to each of the plurality of blocks constituting the image file. The information processing device includes: a first mount processing section mounting the image file to which the metadata including the signature is added at a first mount point, and recognizing the image file; and a second mount processing section mounting the recognized image file at a second mount point, and recognizing the plurality of files included in the image file.
