What Is a RAR File?

A RAR file is a compressed archive file format developed by Eugene Roshal, a Russian software engineer, in 1993. The RAR format is designed to store multiple files within a single archive while reducing file size through advanced compression algorithms. This makes it ideal for sharing large amounts of data over the internet or storing backups efficiently.

RAR files are characterized by their smaller size compared to uncompressed files and their ability to span across multiple volumes. This means you can split a large RAR archive into smaller parts, making it easier to transfer or store. Additionally, RAR files support built-in encryption and password protection, adding a layer of security to your archived data.

How Did RAR Files Originate?

The RAR file format was created by Eugene Roshal and was first implemented in the WinRAR software. Roshal aimed to develop a more efficient alternative to existing archive formats like ZIP. The name "RAR" is derived from Roshal's surname, emphasizing its proprietary nature. Over the years, the RAR format has gained widespread popularity due to its superior compression ratio and versatile features.

Features of RAR Files

RAR files are packed with features that make them a robust choice for data compression and archiving. Here’s a breakdown of their key attributes:
