RAR

RAR is a proprietary file compression format used to reduce the size of multiple files or folders for easier storage and transfer. Developed by WinRAR, it consolidates and compresses data, making it more efficient to share or save. RAR files often include features like error recovery, which helps fix corrupt portions, and encryption for security. To access the contents, you need compatible software like WinRAR or other RAR extractors. Overall, RAR simplifies file management by packaging and compressing data into smaller, organized archives.
