Problems solved by technology

[0006] The present invention provides a management method and system for FLASH files in a flash memory, which are used to solve the problem that the FLASH files in the prior art need to dynamically allocate file space, which is easy to generate space fragments, resulting in unnecessary failures caused by additional management. The problem of instability also further solves the inconvenient and inflexible use of FLASH files in the prior art, and lacks the deficiencies of many file operation functions; potential threat of

Embodiment Construction

[0048] According to the application simplification implementation scheme on the flash memory, the present invention statically plans the space of all files on the flash memory and manages them in a unified manner, so as to achieve the purpose of simplicity, practicality and stability. The present invention will also provide the basic functions possessed by all file systems, including file creation, opening, closing, reading, writing, deleting, searching, locating and so on. The specific implementation of the present invention will be described below in conjunction with the accompanying drawings.

[0049] figure 1 It is a schematic diagram of the implementation process of the management method of the FLASH file in the flash memory of the present invention, as shown in the figure, the implementation process is:

[0050] S101, detecting the FLASH file in the flash memory;

[0051] In this step, all necessary files on the flash memory are collected, and the maximum length of the...

Abstract

The disclosed management method for file in FLASH comprises: building index as the first attribute of FLASH file, operating the file by user as the index. This invention overcomes the defect in prior art, eliminates potential threat, and has well stability and generality.

Description

technical field [0001] The invention relates to a file management method and system, in particular to a FLASH file management method and system in flash memory. Background technique [0002] The FLASH file system, as the name implies, is a file system implemented using flash memory FLASH as an external memory. Therefore, the realization of the FLASH file system must consider the characteristics of the flash memory. Flash memory is gradually replacing other semiconductor storage devices and is widely used in mobile electronic products such as mobile phones, personal digital assistants and digital cameras due to its many advantages such as large storage capacity, no loss of data when power is turned off, and rewritable multiple times. As a storage body for storing data and applications, it can move and exchange large amounts of data conveniently and quickly. [0003] The FLASH file system is mostly used in occasions where the number of files is small and the operation is sim...
