The Fat File System has a clear structure, can be managed easily. At the same time, the simplified structure has some shortage, such as low speed. Attempt to use map management and B+-Tree as new ways to improve it, and store and manage the B+-tree index with map. File system comparative test data can be clearly demonstrated: The use of B + tree index significantly improves the query speed of FAT file system.
