About formats
ALZ is a proprietary archive format created by ESTsoft, a South Korean software company, as the native format of their ALZip archiver first released in 1999. The format was designed to address a specific need in the Korean market: splitting large archives into multiple volumes for distribution when email attachment size limits and slow internet connections made transferring large files impractical. ALZ archives support file compression, multi-volume splitting with configurable segment sizes, and basic file organization with directory structures. The format became widely adopted in South Korea, where ALZip established itself as one of the most popular archiving utilities due to its free availability for personal use and localized Korean interface. At its peak, ALZip was installed on a majority of Korean personal computers, making ALZ a common interchange format for file sharing within the country. One advantage is reliable multi-volume handling — ALZ was specifically engineered for splitting and reassembling archives across volume boundaries, a feature that was central to its design rather than an afterthought. The format's tight integration with ALZip provides a streamlined user experience for compression and extraction tasks. While ALZ saw limited adoption outside South Korea due to the availability of universal formats like ZIP and RAR, it remains encountered in files originating from Korean sources and can be extracted using ALZip, 7-Zip, and other compatible utilities.
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.
