Abstract

Disclosed is a computer-readable recording medium recording a file processing program capable of achieving reduction of a processing time. A notifying section sequentially notifies, based on information acquisition instructions from an application, the application of a plurality of data blocks stored in a storing section. An identifier grasping section refers to identifiers of the respective data blocks stored in the storing section and grasps an identifier corresponding to a data block currently notified of by the notifying section. An executing section receives, when the notifying section notifies the application of the plurality of data blocks, data execution instructions from the application and reads out and executes a data block corresponding to an identifier most recently grasped by the identifier grasping section.

Claims

1. A computer-readable recording medium recording a file processing program applied to a file system, the program causing a computer to function as:

notifying means which sequentially notifies, based on information acquisition instructions from an application, the application of a plurality of data blocks stored in storing means;

identifier grasping means which refers to identifiers of the respective data blocks stored in the storing means and grasps an identifier corresponding to a data block currently notified of by the notifying means; and

executing means which, when the notifying means notifies the application of the plurality of data blocks, receives data execution instructions from the application and reads out and executes a data block corresponding to an identifier most recently grasped by the identifier grasping means.

2. The computer-readable recording medium according to claim 1, wherein:

the program further causes the computer to function as temporarily storing means capable of storing at least one of the identifiers, and

the identifier grasping means grasps the identifier read in the temporarily storing means.

3. The computer-readable recording medium according to claim 1, wherein the storing means is detachably connected to the computer.

4. A file processing method applied to a file system executed by a computer, comprising the steps of:

causing notifying means to sequentially notify, based on information acquisition instructions from an application, the application of a plurality of data blocks stored in storing means;

causing identifier grasping means to refer to identifiers of the respective data blocks stored in the storing means and to grasp an identifier corresponding to a data block currently notified of by the notifying means; and

causing executing means to receive, when the notifying means notifies the application of the plurality of data blocks, data execution instructions from the application and to read out and execute a data block corresponding to an identifier most recently grasped by the identifier grasping means

5. A file processing apparatus applied to a file system, comprising:

notifying means which sequentially notifies, based on information acquisition instructions from an application, the application of a plurality of data blocks stored in storing means;

identifier grasping means which refers to identifiers of the respective data blocks stored in the storing means and grasps an identifier corresponding to a data block currently notified of by the notifying means; and

executing means which, when the notifying means notifies the application of the plurality of data blocks, receives data execution instructions from the application and reads out and executes a data block corresponding to an identifier most recently grasped by the identifier grasping means.

6. A computer-readable recording medium recording a functional program applied to a file system, the program causing a computer to function as:

outputting means which, in open processing executed in a state where based on information acquisition instructions from an application the application is sequentially notified of a plurality of data blocks stored in storing means, identifiers of the respective data blocks stored in the storing means are referenced and an identifier corresponding to a data block currently notified of to the application is grasped, outputs as a return value a data block corresponding to a most recently grasped identifier, the open processing executed based on a function call from the application when the application is sequentially notified of the plurality of data blocks.
