Embodiment Construction

[0036] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0037] In the embodiment of the present invention, a folder is used to simulate a large file, and a series of content sub-files are set up under this folder to record the content data of the large file, and a special information sub-file is set up under the folder to record the content of the large file. Information data, including the logo of the large file, the number of content sub-files, the size of each content sub-file, etc., is equivalent to the directory entry of the file, and at the same time provides users with a unified operation interface for operating large files. These interfaces will ...

Abstract

The invention provides a method for organizing files. The method comprises the following steps that: a. a folder of pseudo files is established; b. an information subfile for recording the information data of the file and more than one content subfiles for storing the content data of the file are established under the folder. An FAT file system can support such a big file greater than 2GB organized by the technical proposal of the invention and the operation efficiency of the big file is the same as that of the operation of a small file.

Description

technical field [0001] The invention belongs to the technical field of data storage, and in particular relates to the storage and read-write operation technology of large-capacity files. Background technique [0002] With the advancement of science and technology, the capacity of data storage devices is increasing, and the files stored in them are also increasing. Therefore, the management system for files in storage devices also needs to support the increasing demand for files. [0003] The file system is the method and data structure used by the operating system to specify the files on the disk or partition. The existing FAT (File Allocation Table) file system and the Ext2 file system are two file systems that are widely used. The files provided by the file system support operations such as opening, closing, reading, writing, and positioning. [0004] As mentioned above, the increase of storage capacity also leads to the increase of files to be stored, but the maximum fil...
