文件系统功能概论
1)本文件系统兼容FAT16/FAT32文件系统格式，支持长文件名，多级子目录，多盘操作，读写，创建删除文件等等功能。
2)本文件系统采用C代码编写，可以方便的移植于计算机应用平台，一般只需要额外编写磁盘的读写驱动，就可使用文件系统所有的功能。
3)具有文件缓冲功能：1）读文件时，读位置在文件缓冲区内，则可直接读取文件缓冲区，不需要读物理磁盘；文件缓冲区大小可使用编译宏EnableFileBuf，TotalFileBUFsQTYeachFCB，FileBUFSize来控制。
4)支持同时打开最多达254个文件；并且最大可打开文件数可由编译宏MaximumFCB设定。
5)支持多任务文件操作的功能：文件可同时同时被多个任务打开，但只有其中第一个打开文件的任务可以得到文件的完全读写权限，以实现文件在多任务环境下的并发操作的保护。

demo代码只支持FAT16
Introduction to File System features
1) The file system compatible format FAT16/FAT32 file system to support long file names, multi-level subdirectory, many disk operations, read and write, create delete files and so on function.
2) The file system used to prepare C code can be easily transplanted into the computer application platform, which generally required to prepare additional disk drives to read and write, you can use all the functions of the file system.
3) has the file buffer functions: 1) read documents, read the location of the buffer zone in the document can be directly read from the file buffer, do not need to read physical disk file buffer size can be used to compile macro EnableFileBuf, TotalFileBUFsQTYeachFCB, FileBUFSize to control .
4) supported at the same time open up to 254 documents and the largest number of documents can be opened by the macro compiler MaximumFCB settings.
5) Supporting file operations mission many features: documents can (2009-03-16, C/C++, 673KB, 下载64次)
