RAR Archive
RAR is a proprietary archive file format supporting data compression, error recovery, and file spanning.
What is RAR Archive?
Developed by Eugene Roshal and introduced in 1993, the RAR (Roshal Archive) format is widely used for combining multiple files and folders into a single compressed container. It is primarily associated with WinRAR, though many third-party utilities can extract its contents. The format supports advanced features like solid compression, robust encryption, and recovery volumes for repairing damaged archives.
