How to zip and unzip files in Windows shouldn't be a major issue for you if you've got WinRAR 32 bits. This is one of the most popular tools to work with zipped files as it's almost an essential tool on any computer.
As you already know, you can reduce the size and weight of any file, email attachment or any other documents you have to upload or download from the Internet. And it's obviously not the only program of this nature: WinZip, 7-Zip, IZArc... but this is one of the most powerful and versatile solutions.
Compatible with different compression formats
Although its name refers to the RAR format it isn't the only one it can work with. In fact, it can open files with other extensions such as ARJ, CAB, JAR, ISO, TAR, JAR, ISO, ZIP or 7z. Nowadays, it's a must since any file you download from uTorrent, Mega or by email is probably zipped.

Why would I want to zip a file or pack of documents?
Apart from saving space (which will depend on the type of file that you're working with, not all files suffer the same compression), you should be interested in zipping your files for security and privacy reasons. You can encrypt any document by means of a password and digital signatures so that only people who know that password can access the original document.
WinRAR, available in multiple languages and 32 and 64-bit versions
These two features have made it one of the most popular programs among millions of users: available in dozens of languages and optimized for all kinds of processors, which makes it suitable to be installed on Windows XP, 7 or 10.
But also other features, such as its integration into the contextual menu of our operating system or the verification of corrupt files: if you work with a file that has any kind of problem, this tool will warn you.
