Embodiment Construction

[0045] Such as figure 1 As shown, the file system conversion access method of an embodiment of the present invention includes the following steps:

[0046] Step S101, information acquisition step: acquire the file system of the accessed external storage device, and acquire the target file system of the accessed target host;

[0047] Step S103, system identical judging step: judging whether the file system is the same as the target file system;

[0048] If no, execute

[0049] Step S105, the mapping relationship establishment step: obtain the file directory list of the external storage device connected, read the file directory list of the external storage device according to the file system format of the external storage device, and map the file directory list of the external storage device is a file control table recognized by the target file system;

[0050] Step S107, conversion step: virtualize the files and file target list of the external storage device into a recognizab...

Abstract

The invention relates to a file system conversion access method and file system conversion access equipment. The file system conversion access method comprises the following steps of: acquiring a file directory list of accessed external storage equipment; reading the file directory list of the external storage equipment according to a file system format of the accessed external storage equipment; mapping the file directory list of the external storage equipment into a file control table which can be identified by a target file system; and virtualizing files and a file target list of the external storage equipment into a format or a compatible format which can be identified by a target host according to a mapping relation. According to the file system conversion access method and the file system conversion access equipment, software installed for accessing a compatible file system on the target host, i.e. a computer, is avoided through providing the file system conversion access equipment, that is to say, non-compatible file system access supporting software is not needed to be installed, and the access of the non-compatible file system in the external storage equipment can be directly finished through the file system conversion access equipment, which is not only convenient for file access, but also can be used for greatly improving the safety of system access.

Description

technical field [0001] The invention relates to an access method of an incompatible file system, in particular to a file system conversion access method and a file system conversion access device. Background technique [0002] Due to the reliability requirements of industrial sites, some highly reliable file system formats will be used; embedded systems will also use corresponding file system formats according to different systems; file system formats used between different operating systems may also be incompatible. Especially in vehicle-mounted equipment, such as digital video recorders, etc., it is necessary to ensure that the data is not destroyed when the vehicle is turned off or the equipment is powered off or suddenly powered off. The reliability of data storage and backup is high, and the file system format with high reliability is generally used. This causes inconvenience when reading data. [0003] In order to enable the operating system to access the non-compatib...
