About formats
ACE is a proprietary compressed archive format created by Marcel Lemke around 1998, primarily associated with the WinACE archiver for Windows. The format gained popularity in the late 1990s and early 2000s due to its strong compression ratios, which were competitive with RAR and often superior to ZIP on many data types. ACE archives support multiple compression levels, solid archiving (treating multiple files as a single stream for better ratios), multi-volume splitting for distribution across size-limited media, recovery records for repairing damaged archives, and password protection. The format uses a proprietary compression algorithm that combines dictionary-based and statistical methods, optimized for general-purpose file compression with particular effectiveness on executable files and structured data. One advantage was the compression efficiency — ACE frequently produced smaller archives than contemporary ZIP implementations, making it popular for file distribution on bandwidth-constrained dial-up era internet. The solid archive mode provided another strength by exploiting redundancy across multiple files, substantially reducing total archive size when bundling files with similar content. WinACE development ceased in the mid-2000s, and a critical vulnerability discovered in 2019 in the widely-used unacev2.dll library led many archiving tools to drop ACE support. The format is primarily encountered today in legacy archives from its peak usage period.
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.
