Fast data exchange system between different type computer and medium storing program of extent information and transformation

摘要

Fast exchanging and sharing a file between plural computers operating by different type operating systems (OS) are capable, even if disk space allocation system is unknown for OS.Extent information locating places of files in a disk drive is extracted independent of file systems (which are programs managing files), the extent information is transformed the device driver for the access request to a file. Accessing to a disk drive is implemented by an extent information extracting.transforming interface program with an extent information extracting.transforming program acting as a device driver.
