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...
