In the embedded field, FAT32 file system with high portability and flexibility is needed to apply to a variety of hardware storage devices.Therefore, a file system design meeting this requirement is adopted.The whole design adopts hierarchical design, which is written in C language and only depends on the calls of a few standard C library functions, so that the code of the file system itself is not only separated from the specific hardware platform, but also independent of any operating system.Thus, it can be easily and flexibly transplanted to the environment with or without operating system support.
