What is a RAR file?
A .rar file extension indicates a compressed archive file that stores one or more files and folders at a high quality and allows important information to be quickly extracted. RAR is short for Roshal Archive — named after the inventor of the file extension, Eugene Roshal.
What are RAR files used for?
RAR compressed files allow users to download, extract, or store multiple files with speedy transfer and download times. RAR files are used for tasks such as downloading your data from Google or Facebook and storing video, audio, or image files.
RAR also allows you to send vast, complex file directories by splitting the compressed data into multiple RAR files known as volumes.
RAR vs. ZIP: What's the difference?
The main difference between RAR and ZIP files is that ZIP is more common. This is because ZIP creation is supported by most operating systems, while you can create a RAR file only using WinRAR, a proprietary third-party software.
Of the two archive file types, RAR typically offers better compression, although compression ratios vary for RAR and ZIP depending on the file types contained in the archive.
Here are some more differences between the two types of compressed files:

Are RAR files safe?
RAR files are generally safe. However, RAR files could contain malware or harmful viruses — the same is true for any file type. Malicious code can only infect your device if the files are successfully extracted, so only extract data from a RAR file that you receive from a trusted source.
Installing a free antivirus solution can add another layer of protection by scanning files before you access them. When sending a RAR file, an antivirus tool can also help you protect your files from prying eyes and stealthy attacks, such as man-in-the-middle attacks. And, don’t forget to password protect your file with a strong, unique password for added privacy.
How to add a password to your RAR file
It’s possible to add a password to your RAR file as you create it. But once the RAR is created, you can’t add a password unless you create the file again. Here’s how to add a password to a new RAR file:
-
Select the files you want to compress in WinRAR and click Add. Then click Set password.
-
Type your chosen password twice, once in each text box. Check the box named Encrypt file names and click OK.
-
Click OK to create your password-protected RAR file.
