What is a RAR file?

RAR (Roshal Archive) is a proprietary archive file format developed by Eugene Roshal that supports data compression, error recovery, and file spanning. It utilizes a variation of the LZSS algorithm with a sliding window size of up to 4 MB (in RAR4) or 1 GB (in RAR5), combined with Huffman coding. Key technical features include support for AES-256 encryption, BLAKE2sp hash algorithms for file integrity, and specialized recovery records that allow for the reconstruction of damaged data. The format structure supports solid archiving, where multiple files are treated as a single continuous data stream to improve compression ratios.

How to open a RAR file

Due to the proprietary nature of the RAR licensing, creating RAR files requires licensed software (WinRAR), though extraction is supported by various free tools. Windows users typically use WinRAR or 7-Zip to extract contents. macOS users can utilize The Unarchiver or Keka. On Linux, the non-free unrar package or the open-source 7z (p7zip-full) package provides extraction capabilities via the command line.

What is a ZIP file?

The ZIP format is an archive file format capable of lossless data compression, originally created by Phil Katz of PKWARE. It utilizes a Central Directory structure to catalog files and supports various compression algorithms, most notably DEFLATE (RFC 1951). The format is standardized under ISO/IEC 21320-1:2015 as a document container file and serves as the base structure for modern file types like .docx and .jar.

How to open a ZIP file

The ZIP format enjoys universal native support across all major operating systems, including Windows (File Explorer), macOS (Archive Utility), and Linux. No third-party software is strictly required for basic extraction, though power users often employ tools like 7-Zip or WinRAR to access advanced features like AES-256 encryption or multi-volume spanning.
