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.XZ is a compound archive format combining TAR archiving with XZ compression, developed by the Tukaani Project and led by Lasse Collin since 2009. The TAR layer bundles files preserving Unix metadata, and XZ applies LZMA2 compression within a robust container featuring CRC-32 and CRC-64 integrity checks, padding support for media storage, and a stream/block structure enabling parallel decompression. LZMA2 improves on LZMA with better handling of incompressible data and multi-threaded compression support. TAR.XZ has become the preferred distribution format for many open-source projects — the Linux kernel, GNU core utilities, and numerous other packages ship their source tarballs as .tar.xz files. One advantage is the best compression-to-decompression-speed ratio among widely supported formats — XZ achieves compression ratios comparable to 7Z while decompressing faster than bzip2, an ideal combination for software distribution. The built-in integrity verification is another strength: unlike raw LZMA streams, the XZ container includes checksums that detect corruption before data reaches the application layer. GNU tar supports TAR.XZ natively via the -J flag, and xz-utils are packaged in every major Linux distribution. The format has effectively replaced TAR.GZ and TAR.BZ2 as the default for source code distribution in the open-source ecosystem.
