Abstract: Due to the variety of operating systems used in the embedded software development and the application correlation of embedded software, the embedded operating system is commonly encapsulated to impove its functions in the embedded software development platform. The function of file system in an embedded operating system is too simple to satisfy the function demand of complicated software such as the communication application software. In this paper a file system schema which combined file management, memory device, FTP server and foreground-background communication mechanism was presented and its implementation based on VxWorks was analyzed. In addition, the programming interface of the scheme was suggested.

Key words: embedded OS, file system, operating system support layer
