7-zip is a very very small program which you can use to zip files. It does not only do zip files, it also does tar files, rar files and pretty much all those different formats that you can use to compress files. Plus it also has an own format which is called 7z. That 7zip format is very, very powerful. It’s very efficient, has a high compression rate, and you see more and more programs using this to pack their setup routines or to make their installation files smaller.
7-zip is an open source program which means you are completely free to use it for whatever purpose. It nicely integrates into your windows explorer. Basically, I use that program in windows because I hate the way the zip integration is done in Windows. It’s not efficient, it takes a long time for zip files to get encoded and to get compressed and to get decompressed. You don’t have any options. And basically it only does zip.
7-zip is the way zip files should be integrated into Windows. It’s very small, it’s very efficient. It doesn’t take much resources. It’s very secure. It’s easy to use, which to me is very important. So that’s it pretty much. I recommend that if you’re on a 64 bit version of Windows. You actually do download the 64 bit version of 7 zip. It just gives you a little bit of extra power. But the 32 bit version is also fine. If for some reason you want to use that.
