A RAR (Roshal Archive) file is a proprietary compression format that reduces file size to save storage space and speed up internet transfers. Unlike standard ZIP files, RAR files often provide better compression ratios and advanced features like:

: Large datasets can be split into smaller parts (e.g., .part1, .part2) for easier sharing. Need to open, create, or convert a RAR file? - WinZip
