 Zip File

Zip File

  • The zip file extension doesn't have a full form. It's an archive file format that supports lossless data compression (original data perfectly reconstructed from compressed data).
  • There's variety of data compression algorithms available like deflate, Huffman coding, arithmetic coding, Lempel-Ziv-Markov chain algorithm (LZMA), etc.
  • A zip file might be understood because the combination of multiple compressed files and folders, sometimes combined together to make an archive.
  • Phillip Walter Katz is that the co-creator of the zip file format and was initially released on February 14, 1989. The informal meaning of zip is “move at high speed”.

Characteristics of zip

  • Zip file format uses the file extensions .zip or .zip and therefore the mime media type application/zip.
  • Zip file format is used with any OS like windows , MAC and Linux systems.
  • Zip file supports password based authentication called Zipcrypto to avoid unauthenticated people reach.
  • There are various .zip tools available like WINZIP, WINRAR , 7-zip , etc. To make a zip file, or to unpack the contents of a zip file.

Aim

  • The main aim of zipping is data compression.

Data compression

  • Data compression may be a way of encoding structured data to require up less disc space when stored on a computer-based system. Basically, it involves re-encoding information using fewer bits than the first representation.

Advantages of zip

  • By using zip file format one can compress the files and folders to a large extent and may save to 80% or more in hard disk space.
  • Transmission of zipped files over the web is far easier and drastically reduces the e-mail transmission time.
  • Zipping supports encryption of data, helpful when sending private data over the web.
  • The minimum size of a zip file is 22 bytes. Such an empty zip file contains only an end of central directory record (eocd).
  • Zip maintains privacy - zipping allows you to encrypt private data, helpful when sending such data over internet.
  • Zip improves file integrity.

Disadvantages of zip

  • Uncompression of files takes up memory and processor time to finish the task, running within the background. You’ll encounter out of memory error.
  • Sometimes there is also an opportunity that zip file get corrupted and extraction of files and folders cannot happen correctly.
  • In some situations including compressing video and audio files, the file you're compressing can't be made smaller, leading to a compressed file that's larger in size than the first file.
  • Damaged data can affect the whole zip file.
  • Unencryption can occur.
