What is a zipper File?

Zip is an archive system that packs one or more computer files into one file or folder and takes up less space than the first file.

The zip file is usually called the "archive" file. The zip file is really sort of a container… during which the important files are kept.

The purpose behind the zip file is transportation and storage. Keeping multiple files within the same folder makes it easier to store and transport them. Also, ZIP files are compressed and thus take less space to store them.

Extensions of .ZIP files are usually ".zip" or ".ZIP".


Why Do People Use Zip Files?

Zip files compress data and thus take less time and space to download them from the web or attach to e-mail. Zip files are used for these specific uses:

Distributing files over the Internet: just one download is required to receive all related files, and file transfer is lost as archive files are compressed.

Disk space is saved: If you've got large files that are important but rarely used, compressing them in Zip saves space for storing .


History of Zip:

The .ZIP file format was created by Phil Katz of PKWire and Gary Conway of IDC (Infinity Design Concept, Inc.). They created the format after PKWire's System Enhancement Associates (SEA) filed a lawsuit filed against them, claiming that their storage products were derivatives of SEA's ARC storage system. SEA also threatened to sue Gary Conway and IDC for an equivalent reason, on the other hand acknowledged that SEA's work was actually break away IDC's work and preferred to not pursue the lawsuit.

The name "zip" (meaning "move at high speed") was suggested by Robert Mahoney, Kataj's friend. They wanted to point that their products were faster than ARC and other compression formats of the time. The earliest known version of the .ZIP file format specification was first published in 1989 as a part of the PKZIP 0.9 package under the file APPNOTE.TXT.


How Do Zip Files Work?

A Zip file receives three things:

It bundles one or more files into a container file.

Its content is compressed as short as possible, it are often reduced to 90%.


When you compress files, the compression program will scan the file to compress repeated pieces of data .


Let's take a really simple example to know this easily. Suppose you've got this one file -


"1110101001001000000000000000000000000000000000000000000001100101001"


So this file are going to be compressed as follows -


"1110101001001 (insert 40 zeroes) 1100101001"


When you unzip this compress file, this program will restore the first file by adding 40 zeroes rather than insert 40 zeroes.


How to make a well Compressed ZIP file?

Design of Zip :

.ZIP files are archives that store multiple files. .ZIP files are compressed using several different methods, also as files which will be stored without being compressed.

Each file is stored separately, different files are often compressed within the same archive using different methods. Since files during a ZIP archive are individually compressed, it's possible to extract them, or add a replacement file, without applying compression or decompression to the whole archive.

A directory is placed at the top of the .ZIP file. Identifies which files are in .ZIP and where .ZIP is found therein file. this enables .ZIP riders to load an inventory of files without reading the whole .ZIP archive.

The .ZIP archive may include additional data that's not associated with the .ZIP archive. this enables a .ZIP archive to be created into a self-extracting archive (an application that decompresses its own data).


What about RAR, ARJ, TAR files?

Many different sorts of compressed files are available today. The principal of every is analogous thereto described above, but each compression format has its own benefits.
