The 7-zip compression utility is well known and has been a stable platform that is still free unlike others that have now become ‘buy now’. The 7-Zip compression utility is much easy to use that the normal zip archive and is a rival to Winrar which is very widely used. The following is what the software can do.

If you are looking for more software for file compression then check the list of other compression software which is hosted on this website. As stated the Winrar program is by far the most widely used compression utility on the market and much like 7-zip it is free. There is a mirror for 7Zip here.

Install: 7-Zip

The installation of 7-Zip is very easy and straightforward. The software can be installed with other compression programs and they do not interfere with each other. Like most compression software you do get an option during the install as to which files you wish to associate with 7-Zip. Those files will then only be opened by 7-zip or you can allow it to open all files.

Running: 7-Zip

I discovered 7-Zip about 4 years ago and the reason why I liked it was because it could open a damaged Zip file which the others could not open. That was its first attraction. Much like other programs it comes with many language options and it compression ratio I have found to be about 2% on massive picture files.

As you can see the options in the directory when you ‘left-click’ on a file. You can open the archive, extract it into the directory where the file is located or create a directory for the file which is very useful. The program also gives you an option of .z and zip and will email the program for you as well. This is a good option when it comes to getting work done on the fly. There are 3 mirrors listed below where you can download the latest version.
