Understanding the RAR File Format: Efficiency in Compression
The format has evolved over time. RAR4 (sometimes referred to as version 2.9) was the standard for many years until the introduction of RAR5 [6]. The newer RAR5 format offers even better compression, larger dictionary sizes, and improved data recovery [18]. While "04

It has since become one of the most widely used methods for compressing and bundling files, often favored over the standard ZIP format for its advanced features and superior compression ratios. 1. How RAR Works
