本文件系统实现的一个类似于DOS/WINDOWS的文件管理系统，可方便的移植于各种嵌入式系统平台。本文件系统采用了文件缓冲块的技术，文件读写速度被加快。本文件系统可支持多个逻辑盘，可以方便的实现不同逻辑盘之间数据的搬移。本文件系统支持子目录，长文件名，为此，增加了许多额外的代码，使文件系统的整体开发变得复杂，但对上层来说应用变得简单，灵活，扩大了本文件系统的应用领域。本文件系统采用模块化的设计技术，因些性能稳定，构架清晰，系统二次开发方便。-This document is a system similar to DOS/WINDOWS file management system can facilitate the transplantation in a wide variety of embedded system platform. This document is a file system buffer block technology, was to speed up file access speed. The file system can support multiple logical, to facilitate the realization of data between different logical move. Subdirectory of the file system support, long file name, to that end, an increase of a number of extra code, so that the overall development of the file system has become complex, but for the application of the upper simple, flexible, and expand the file system application领域. The file system using modular design techniques, due to more stable performance, clear fr a mework, the system to facilitate the secondary development.
