Abstract

An embodiment of the present invention provides a file management method for a storage medium without a file system. The method includes: establishing a storage space management database in the storage medium; responding to a write instruction of the file to be stored, obtaining the file name and file size of the file to be stored; checking whether the file name of the file to be stored exists in the file management table; if If it does not exist, allocate a specified storage address for the file to be stored according to the free storage address management table; record the file name, storage address and file size of the file to be stored in the file management table, and write the file to be stored to the specified storage address. The embodiment of the present invention also provides a file management system for a storage medium without a file system. The embodiment of the present invention records and manages the storage space of the storage medium without the file system by using the file management table and the free storage address management table of the database, provides the cross-platform performance of the storage medium without the file system, and improves the reading and writing speed.

Description

technical field [0001] The invention relates to the technical field of file management systems, in particular to a file management method and system for storage media without a file system. Background technique [0002] The high-speed and large-capacity solid-state storage system is mainly composed of control chips and Nand flash. The performance of the control chip directly affects the performance of the storage system on the management capability of the Nand flash firmware, and the data processing control algorithm it uses will directly lead to a huge gap in various indicators of the high-speed and large-capacity solid-state storage system. The controller of the high-speed and large-capacity solid-state storage system is a built-in processor that runs refreshable firmware. The controller is used to communicate the stored data with the computer. Generally, the computer program developer specifies the address and data length to be written. Through The controller completes t...
