INTRODUCTION
File compressor is a system based software
The software will be done using core java
It can use in the system as a utility
The type of compression we use is called loss less compression
EXISTING SYSTEM:
Current system supports manual compression.
User needs to compress the file externally when he wants to save the memory
The File is externally decompressed to view the contents of file.
DISADVANTAGES:
Every file has to be compressed and decompressed externally ,which is very time consuming.
The user depends on third party software's like WinZip ,Wirer.
PROPOSED SYSTEM:
Automatic compression is done when the file is saved to hard disk and saves the memory
File decompression is done automatically when the file is opened.
An efficient algorithm is used to compress and decompress the file,so no third party is needed.
ADVANTAGES:
No time is needed to compress or decompress the file.
Greater efficiency and Better service.
Compression is loss less compression.
Validation Testing:
This testing concentrates on confirming that the software is error-free in all respects. All the specified validations are verified and the software is subjected to hard-core testing. It also aims at determining the degree of deviation that exists in the software designed from the specification; they are listed out and are corrected.
System Testing:
This testing is a series of different tests whose primary is to fully exercise the computer-based system. This involves:
Implementing the system in a simulated production environment and testing it.
Introducing errors and testing for error handling.
