What is an LZO file?
The LZO (Lempel-Ziv-Oberhumer) format represents data compressed using the LZO library, a lossless data compression algorithm developed by Markus F.X.J. Oberhumer. Unlike algorithms optimizing for space, LZO prioritizes decompression speed, suitable for real-time applications and data streaming. The file format typically acts as a container for data blocks compressed with LZO1X or related variants, focusing on extremely fast decompression and low memory footprint rather than maximum compression ratios. It is often generated by the lzop utility, which wraps the raw LZO stream with a header containing checksums (Adler-32 or CRC-32) and file metadata.
How to open an LZO file
Opening LZO files requires software that implements the LZO library. On Linux and Unix-like systems, the lzop command-line utility is the standard tool for extraction. Windows users lack native support and must rely on third-party utilities such as PeaZip or Universal Extractor which integrate the LZO decompression libraries. 7-Zip can open LZO archives if the requisite plugins are installed or if the file is a tar.lzo container.
