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.

What is a 7z file?
The 7z format is a compressed archive container created by Igor Pavlov in 1999, characterized by an open architecture and high compression ratios utilizing the LZMA and LZMA2 algorithms. It supports file sizes up to 16 exbibytes (2^64 bytes), Unicode file names, and strong AES-256 encryption, with solid compression capabilities to enhance efficiency for similar file sets. Distributed under the GNU LGPL, the format's modular design accommodates various pre-processing filters and encryption methods, establishing it as a primary standard for high-efficiency data archival.
How to open a 7z file
While Windows 11 builds utilizing the libarchive project offer native support, earlier Windows versions require the official open-source 7-Zip utility or alternatives like WinRAR and PeaZip for extraction. macOS users typically rely on third-party software such as The Unarchiver or Keka, whereas Linux distributions handle 7z archives via the p7zip package accessed through the command line or GUI managers like File Roller.
