Design and Implementation of a FITS File Manager

The software package FITS File Manager(FITS Manager)is mainly for managing small and medium number of FITS files,providing quick search,preview,and related processing functions.The FITS Manager adopts advanced technologies for the Virtual Observatory without changing working habits of astronomers.The development mode of the FITS File Manager is through the increasingly popular plug-in based architecture,which easily achieves cross-platform and scalability.In the FITS File Manager,all application functions are accomplished by plug-ins,and a core component provides a simple interface for the plug-ins to enhance the reusability of common functions.With more plug-ins for a variety of applications developed and contributed from the user community,the FITS File Manager will become an efficient platform for astronomers to handle FITS files.
