What is RAR?
RAR (Roshal ARchiver) is a proprietary archive file format that supports data compression, error recovery, and file spanning. It was developed by Eugene Roshal and is commonly associated with the WinRAR software utility, which creates and manages RAR archives. RAR files are known for their superior compression ratios and advanced features compared to other archive formats.
File Format: RAR files use .rar extension and are proprietary format requiring licensed software for creation. However, RAR files can be opened and extracted by various third-party tools and online viewers.
Compression: RAR typically achieves better compression ratios than ZIP, with compression rates of 70-85% depending on file type. Uses advanced algorithms including LZSS, PPM, and specialized filters for multimedia files.
Structure: RAR archives consist of variable-length blocks starting with a marker block and archive header. Supports solid archives (multiple files compressed as one continuous data stream) for improved compression.
Features: Includes AES-256 encryption, multi-volume archive support (splitting large files), error recovery records, and Unicode support for international filenames.
Versions: Two major format versions exist: RAR4 (older, versions 1.5-4.0) and RAR5 (introduced in WinRAR 5.0, 2013). RAR5 improved compression, added better recovery records and increased maximum dictionary size to 1GB.
