What is a tar.lzo file?

The tar.lzo format combines the POSIX-compliant Tape Archive (tar) container with Lempel-Ziv-Oberhumer (LZO) lossless compression. Developed by Markus F.X.J. Oberhumer, the LZO algorithm utilizes an LZ77-based approach prioritized for extremely fast decompression speeds rather than maximal compression ratios. The file structure encapsulates a standard uncompressed tarball within an LZO stream, allowing for rapid real-time data extraction often used in embedded systems or disk cloning operations where CPU throughput is the bottleneck.

How to open a tar.lzo file

Native support for tar.lzo is limited on standard operating system kernels without specific libraries. On Linux, users can extract these archives using the GNU tar command combined with the lzop package (command: tar --lzop -xf file.tar.lzo). For Windows users, 7-Zip does not natively support LZO; therefore, PeaZip is the recommended technical solution as it integrates the necessary lzop binaries. macOS users can utilize The Unarchiver or install lzop via Homebrew.

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.
