Zip files are simply compressed versions of
normal files. Much of the software which you can download from the
internet is in a zip format. This reduces the file size and therefore
makes the download of software faster. Zip files also allow multiple
files to be zipped together in to one zip file package, so that instead
of having to download many different files, you can just download the one
zip file. Then, you open the zip file, the multiple files can all
be emptied out in their original format to one folder on your computer

So how do you use zip files? Well, you
will need an unzipping program to use them. One of the best unzipping
programs is a free-to-try utility called Winzip ...
This window shows that the zip file " macaroni.zip
" contains 4 separate "normal" files. It also shows how much file
space was saved when the files were put into the zip file, for example
File_id.diz was reduced in size from 432 bytes to 276 bytes when zipped,
a saving of 36%.
You can download a free trial version of the latest version of the Winzip program from the Winzip home page. You can try it out for 28 days before the free period expires. At the end of this limited time trial you need only pay one small fee to be able to continue using the program to unzip or to zip files as often, and for as long as you like. Once you have downloaded the free-to-try Winzip
software, the easiest way to use it for most programs is to set it to Winzip
"wizard" mode. Then, when you double click on any .zip file held
on your computer, the Winzip software will automatically unzip the .zip
file and place the unzipped file(s) into one separate folder.
