On clicking on Open Button, File Open window appears in which we can provide name of existing zip file for which we want to view the contents of zip. Once we have chosen name of zip file and press enter, detail of zip file entries (files included in zip file) will be displayed in table which is added on first screen (Entry Window). Table shows name of the file, size of the file, last modified date and time, compression ratio and other attributes.

The system developed using JDK1.5 and Oracle fully meets the objectives of the system. The system has reached a steady state where all the bugs have been eliminated and the operators and the users have been thoroughly trained in the operation of the system. The system is operation at the high level of efficiency and all the parties associated with the system understand its advantages. The system solves the problem it was intended to solve as the requirement specification phase.
Though the system is completed for the current requirements but its open for future extension. Various future extensions are identified for the system, which might be thought as limitation of the current system.
Thus, in the end I would like to conclude that an automated system has become a need for every organization, and sooner or later every one will be compelled to install it due to its numerous advantages.
