How to Open a Rar File

You just received a file through your computer that has an extension you've never seen before. It's a "Rar" file. What is this thing? And more importantly, how can you open it to see what it is that someone you know has sent to you? Don't worry; the name may be strange and the file may be different but the process for opening it is something that you've probably done plenty of times before. And even if you haven't, it's a relatively easy thing to learn how to do.

But first, what is a Rar file? Why are you even receiving this thing?

A "Rar" file is basically just another name for a "Zip" file. You've surely sent and received Zip files before so you know that they take the information you are trying to send and compress it in order to reduce the size of the file to make sending it over the Internet easier. If you've unzipped a zip file, you know that the material looks basically the same as it did in its bigger format; it was just reduced so that it could be attached to email. A "Rar" file is basically the same thing.

So why not just call is a Zip file?

Okay, okay, the "Rar" file is a little bit different than a Zip file. The way that the file is compressed differs in that it uses a more complex algorithm for the compression. As far as you're concerned, this doesn't mean much at all. What does matter on your end is that the "Rar" file is compressed to smaller sizes than a Zip file can be so you're able to send more in open file in one email attachment if you use Rar than if you use Zip. That's probably why you're receiving a Rar file. Someone wanted to send you a big file that couldn't be zipped down to an e-mail-attachable size so they sent it as a Rar file instead.

Okay, great, you know what a Rar file is now. So how do you open it?

You'll need to download a program that is capable of opening a Rar file. The most commonly used program for this purpose is probably BitZipper. You can get a free trial download of it online by typing BitZipper into your favorite search engine. There are plenty of other software programs that you can download for free that will also be able to open your Rar file. If you want to play around with your different options, head over to CNET downloads ( and type "open rar" or "open compressed files" into a search. You can download any of the software available that says it can be used to open these files. Once you have downloaded the software, you can follow the simple step-by-step instructions available on the program to complete opening of the Rar file. If you're not too good at things like this, make sure that the program you download has a "Wizard" interface. That's the step-by-step thing that will run you through an easy method of using the program. It's as easy as telling a Zip file to unzip.

Be careful here. RAR is a popular format for sending virus infested files. So before you click on a .rar file, you should check it with your anti-virus first.

one of the advantage of RAR file is that it compress the file and save you bandwidth while sending it online.

WinMount can mount RAR files on a new drive, so that you can use files inside it directly. There is no extraction time before you use them, and you don't need disk space to hold these huge files. WinMount saves your time and disk space! (

or decompress rar with winmount ( )

I downloaded an album today and it is in .rar format. I used winrar for that, but the uploader made it where you have to create a password to access files. I read a tutorial about "Adding to Archive" and making a password but to no avail, I still get this error, "CRC failed to encrypted files". Does anybody know the solution, I've have been trying to listen to this album for a year. You can send your replies to or just here too. Thanks and Peace!

I use WinRAR to open RAR files as well as other compressed file types like ZIP files. Once it's installed, it integrates itself into the Windows shell. Double-clicking on the RAR or ZIP file opens it up so you can see what's inside. Right-clicking it then selecting one of the Extract options in the menu that appears uncompresses the folder/file. (Is "uncompress" a word? :p)

7Zip works best for me. It is free, and in addition to all mentioned formats it can work with tar and gz files, which comes real handy when you run a website or two on UNIX-like platform:)

Very nice explanation of the "rar" file type, which I had also not heard of before. However, you may point out to your readers that they should use caution when opening compressed files from unknown sources. The reason is that most anti-virus packages do not scan within compressed files.

And you can use that 'rar' program to unzip zip files, rar files and many other zipped extensions.

Useful hub for many, Kathryn!
