About formats
7Z is the native archive format of 7-Zip, an open-source file archiver created by Igor Pavlov in 1999. The format uses an open, modular architecture that supports multiple compression algorithms — LZMA and LZMA2 (the defaults), PPMd for text-heavy data, BWT, and Deflate — selectable per file within the same archive. LZMA typically achieves 30-70% better compression ratios than Deflate-based ZIP files on comparable data, making 7Z one of the most space-efficient general-purpose archive formats available. The container structure stores files with full directory hierarchy, timestamps, and attributes, while supporting solid compression (treating multiple files as a continuous data stream) for additional ratio gains on archives with many similar files. Encryption uses AES-256 with key derivation based on iterative SHA-256 hashing, and both file contents and filenames can be encrypted. One advantage is superior compression density — 7Z consistently produces smaller archives than ZIP or RAR on most data types, valuable when minimizing storage or bandwidth matters. The open architecture is another strength: the format specification and 7-Zip source code are publicly available under the GNU LGPL, enabling any developer to implement 7Z support without licensing constraints. Cross-platform tools supporting 7Z exist for Windows, macOS, Linux, and mobile platforms, and the format has gained widespread recognition as the preferred choice when maximum compression is the priority.
TAR.LZMA is a compound archive format combining TAR) archiving with the LZMA (Lempel-Ziv-Markov chain Algorithm) compression method developed by Igor Pavlov for the 7-Zip project around 1998. The TAR layer concatenates files with Unix metadata into a single stream, and the LZMA algorithm compresses it using a sophisticated combination of LZ77 dictionary matching with large dictionaries (up to 4 GB), Markov chain-based probability modeling, and range coding. LZMA was the predecessor to the LZMA2 algorithm used in XZ and 7Z formats. Compression ratios significantly exceed gzip and are comparable to bzip2 while offering substantially faster decompression. One advantage is the high compression ratio with fast extraction — LZMA decompresses at speeds close to gzip while achieving compression densities near bzip2 or better, making it efficient for distribution archives that are compressed once and extracted many times. The format is supported by tar's --lzma flag and by 7-Zip across all platforms. While TAR.LZMA has been largely succeeded by TAR.XZ (which uses LZMA2 in a more robust container with integrity checks), existing TAR.LZMA archives remain encountered in software distributions and backup systems that adopted the format before XZ became widely available.
