S13, responding to an access or operation instruction of a user to the CIRROS file system, and synchronously updating the corresponding directory record file.
In the embodiment of the invention, the partition frame of the CIRROS file system is extracted from the Linux operating system and converted into the directory structure of the Linux operating system, so that the partition directory of the CIRROS file system is established to store CIRROS files with different data types. And establishing a directory record file CIRROS.DIR for each partition directory, wherein the directory record file CIRROS.DIR is used for recording the file information of each CIRROS file in the partition directory. When a user runs and manages the CIRROS file system on a Linux operating system, responding to access or operation instructions of the user, completing access and operation of any CIRROS file, and simultaneously updating corresponding file information in a directory record file CIRROS. DIR of a partition directory to which the CIRROS file belongs according to the operation of the user on the CIRROS file.
Preferably, the file information of the CIRROS file includes, but is not limited to, a file name, a file attribute, a file version number, a file size, and a file last modification date. The file attribute is used for describing the access state of the CIRROS files, and each CIRROS file has 16-bit file attribute and is used for representing the read-only, writable, protected, invisible and other attributes of the CIRROS file. The file attributes are not mutually repulsed and can be simultaneously effective. The file version number is version information carried by each CIRROS file, and the files with the same name can have 99 versions at most, namely the range of the file version v is 1-99, and the files with the highest versions are used by default.
Preferably, the user's operations on the CIRROS files include, but are not limited to, operations on opening, closing, modifying, creating, deleting, copying, and moving the CIRROS files.
Specifically, referring to fig. 2, a flow chart of step S11 in the first embodiment of the present invention is shown, in order to more flexibly and efficiently establish the partition directory of the CIRROS file system to store the CIRROS files with different data types, step S11 in the first embodiment of the present invention is executed through steps S111 to S113:

S133, after the CIRROS file is operated, synchronously updating the directory record file of the partition directory to which the CIRROS file belongs.
After the user performs operations such as opening, closing, modifying, creating, deleting, copying and moving the CIRROS file, according to the operation content and the operation result of the user, the directory record file CIRROS. Dir corresponding to the partition directory to which the CIRROS file belongs also performs updating of corresponding file information, so as to maintain the accuracy and effectiveness of the directory record file.
