The features of a zip file

Written by Mike Roberts. Posted in Computers

ZIP is a type of file that allows compression, without any loss of relevant data. Whenever you see the extension “.zip” on a document, you should know that it consists in one or more files, which have been compressed before being added to the archive. The archiving process is extremely simple, especially for those who use Windows as their operating system: the files may be zipped individually or simply dragged into a folder, and the transformations are made by themselves. This way, the folder occupies less storage space on the hard drive, streamlining any type of file transfer. Using a zip compressor is something more and more computer users do nowadays, taking into consideration the evolution of internet, which offers them the possibility to send and receive data at any time, the only limitation being represented by file size. In case you think you need such a compressor, here are some of its main features that you can take advantage of.

It offers lossless compression

The most common feature of a zip compressor is that it gives you the possibility to diminish the dimension of your files, without changing their quality. When it comes to compression, the process can be divided in two categories: lossy or lossless. The first one is unreliable, because it often leads to data loss – which means that the resulting files are not similar (in terms of quality) with the original ones. A zip compressor will offer you the second type – lossless: whether you need to shrink pictures, music or videos, these will remain faithful to their initial form. The ability of reducing files’ size is the one most people are aware of, as far as zip archives are concerned, but these also have other advanced features no everybody knows about.

 

File encryption

This feature is less common and requires the use of an additional piece of software. While for basic operations, Windows has the ability to zip and unzip any file, when it comes to encryption you will have to download another dedicated program. Encryption is extremely useful if you want to protect your files from other users: in case you do not want somebody else to access your files, you can simply add them to an encrypted zip archive. You will have to use a password (and make sure it is a strong one), in order to foster the security of your documents. In addition to this, you can even encrypt the name of your files, so that no one can see what type of documents you keep in that archive.

 

You can create self-extracting archives

The self-extracting document is similar to a normal zip document, except for the fact that is has the “.exe” extension. This special type of zip archive is even easier to unzip: all you have to do is try to open it, and the consisting files will be automatically extracted. Of course, the opinions regarding this feature are spread, but you can always try it if you consider it more efficient.
