In these devices, it is often necessary to store a large number of files, and file management becomes a basic function that various operating systems must provide. The operating system usually manages and displays the file directory in a file tree structure in which the operating system saves the file tree structure through the device's memory, such as a file index table on the hard disk. In order to improve the efficiency and flexibility of file management, various file management software running on the operating system has been introduced to the market.

Currently, file management software on the market usually provides file management related functions by reading the file index table to display the file tree structure. These functions usually include: displaying all the directories and files in any directory in the file tree structure, displaying the file attributes of the selected file, such as file size, modification date, type, etc., when the user starts global filtering based on file attributes, The file attributes in all files under the display file tree structure contain files set by the user for filtering keywords. At present, when the file management software on the market provides the above functions, it is necessary to read the file index table once or more. For some advanced functions of file management, such as global filtering based on file attributes, it is necessary to further read the file index table according to the file. The location information of the file in the file, and the file attributes in the file header of the corresponding file on the memory are read. It is not difficult to see that when providing advanced functions of file management, the current file management software needs to access the file index table on one or more memories, and needs to access the file header on the memory for each file to obtain the file attributes. When it is necessary to continuously access hundreds or even thousands of files, since a large amount of memory access memory is required, and the access time of the memory is difficult to reduce by an order of magnitude, when the amount of access is increased by one or more The access time of the time-storage memory becomes a major obstacle to the efficient provision of advanced functions for file management, so that current file management software is often inefficient in providing advanced functions for file management, affecting the user experience of file management.
