+NASA core Flight System File Manager Application
+
+## Description
+
+The File Manager application (FM) is a core Flight System (cFS) application that is a plug in to the Core Flight Executive (cFE) component of the cFS.
+
+The cFS is a platform and project independent reusable software framework and set of reusable applications developed by NASA Goddard Space Flight Center. This framework is used as the basis for the flight software for satellite data systems and instruments, but can be used on other embedded systems. More information on the cFS can be found at [http://cfs.gsfc.nasa.gov](http://cfs.gsfc.nasa.gov)
+
+The FM application provides onboard file system management services by processing ground commands for copying, moving, and renaming files, decompressing files, creating directories, deleting files and directories, providing file and directory informational telemetry messages, and providing open file and directory listings.
