Unlock the Secrets of RAR Files: Everything You Need to Know

What is a RAR file?

A RAR file is created by compressing one or more files into a smaller file using the WinRAR software. The .rar file extension stands for Roshal Archive, which refers to a highly compressed file (also known as an archive) that can be password-encrypted.

What are RAR files used for?

RAR files are used to transfer or store huge files, like when you download your data from Google or Facebook, or send gigabytes of data as image, audio, or video files. Compressing the files into a single RAR file lets you speed up transfer and download times.

Sometimes, file size limitations make a single file inconvenient for storing on a drive or sending in an email. In this situation, you can create a multi-volume archive by splitting your compressed data into multiple RAR files, known as “volumes.”

Each volume is numbered in the file name (volname.part001.rar, volname.part002.rar). Then, when you uncompress your files, you need to have all volumes in the same location and extract them in chronological order.

RAR vs. ZIP: What's the difference?

ZIP files are more widely used and flexible, working with any operating system. While both RAR and ZIP can compress large amounts of data, they have differences in how they compress files:

Data compression: RAR uses a higher data compression ratio than ZIP. That means RAR creates a smaller file size than ZIP. It doesn’t take as long to upload or download your RAR file, but it’s slower than compressing the same data using ZIP.

Encryption: Both file formats support password protection, but they use different encryption methods. RAR uses AES-128 encryption, which is generally superior to the ZIP 2.0 encryption algorithm. If you use 7-Zip to create your ZIP files, you get AES-256 encryption, which is more secure than both RAR and regular ZIP files. With RAR, you can also lock encrypted archives to prevent accidental modification of your files.

Error recovery: Like other file types, RAR and ZIP can get corrupted, making the content they contain inaccessible. If this occurs, you can repair the damage using RAR repair software, which allows you to reconstruct damaged data.

Software: Most operating systems have built-in features for opening ZIP files, and there are many free apps available for creating ZIPs. Creating RAR files, by contrast, requires extra software, which makes RAR files a bit harder for some people. Although you need software to create RAR files, many of the data compression applications enable you to convert RAR files into other archive formats — ideal for someone who doesn’t have the necessary RAR opener software.

How to open a RAR file?

To open files ending in .rar you need a special RAR file opener for extracting the data. If you’ve ever downloaded an app to unpack a ZIP file, the same software can usually unzip RAR files too.

Here’s an overview of the most commonly used applications for opening RAR files:

• WinZip: A paid app for RAR and ZIP file management available on Windows, Mac, iOS, and Android. Download it from WinZip, the App Store, or Google Play. Then select Use Evaluation Version for a free trial.

• WinRAR: A paid app for extracting and creating RAR files on Windows. The app comes with a free trial, and you can download it from WinRAR.

• 7-Zip: A free, open-source app with a high compression ratio and its own archive format called 7z. Available for Windows PCs and downloadable from 7-Zip.

• iZip: A free app for ZIP and RAR file management. Available for Mac, iPhone, iPad, and Windows PC. Download it from the App Store or iZip.

The Unarchiver: A free app for unpacking archived files on Mac. Download it from the App Store or The Unarchiver.
