Abstract

An embodiment of the present invention provides a file management method for a fileless system storage medium. The method comprises the following steps of: establishing a storage space management database in a storage medium; obtaining a file name and a file size of a file to be stored in response to a write instruction of the file to be stored; looking for the file name of the file to be stored in the file management table; if not, assigning a designated storage address to the file to be stored according to the idle storage address management table; recording the file name, storage address and file size of the file to be stored in the file management table, and writing the file to be stored to the specified storage address. Embodiments of the present invention also provide a file management system for a fileless system storage medium. The embodiment of the invention provides the cross-platform performance of the fileless system storage medium and improves the reading and writing speedby recording and managing the storage space of the fileless system storage medium by using the file management table of the database and the idle storage address management table.

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...
