Abstract:
"Compression and Decompression" is most common word when you transfer your data from one place to another. Sometimes you have large size of data that can not transfer (e.g. mail attachment). You use a software (Zip) to compress your data and able to transfer it. And on other end, you decompress your data and get the original data.
Developed an application to read existing ZIP files and extract some or all of the files, to create a new ZIP file or to edit existing ZIP file by adding and deleting files and folders or Compress a folders decompress a zip file.
GZIP
This algorithm uses internally the Deflate algorithm. This algorithm includes a cyclic redundancy check value for detecting data corruption. Also it's compatible with most compression tools because it writes headers to the compressed file, so compression tools -like WinZip and WinRAR- can easily access the compressed file and decompress it as well.
