About formats
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.
TGZ (also written as .tar.gz) is the most widely used compound archive format on Unix-like systems, combining TAR) archiving with gzip compression. Gzip was created by Jean-loup Gailly and Mark Adler, first released on October 31, 1992 as a free, patent-unencumbered replacement for the Unix compress utility. The TAR layer bundles files with full Unix metadata (permissions, ownership, timestamps, symlinks, hard links) into a single sequential stream, and gzip compresses it using the Deflate algorithm — a combination of LZ77 dictionary matching and Huffman coding. The resulting .tar.gz or .tgz file is the standard format for distributing source code, creating system backups, and packaging software on Linux and Unix platforms. One advantage is near-universal support — TGZ files can be created and extracted on every Unix system, Windows (via 7-Zip, WinRAR), and macOS natively, making it the safest choice when the recipient's platform is unknown. Fast decompression is another practical strength: gzip extraction is significantly faster than bzip2 or xz, important for CI/CD pipelines, container image layers, and automated deployments where extraction time matters. GNU tar supports TGZ natively with the -z flag, and the format serves as the basis for many higher-level packaging systems. While XZ offers better compression ratios, TGZ remains the default choice when broad compatibility and extraction speed are priorities.
