Better late than never: Microsoft finally introduced native support for RAR archives earlier this year, just three decades after the format's official introduction in 1993. Windows 11 development is now progressing at an accelerated pace, therefore support for a whole lot of new (ancient) archive formats is coming soon.

Windows 11 users can now manage RAR archives natively, with no need for third-party software or questionable archive "unpackers." Windows 11 22H2, the past year's last major release of the operating system (distributed on September 20, 2022), will soon become even more proficient in managing different kinds of archive files and formats.

Microsoft recently released KB5031455, an optional, feature-rich preview cumulative update for Windows 11, refreshing the list of archive formats natively supported in the OS. Windows 11 22H2 and later versions can now manage files compressed in the following archive types: .rar, .7z, .tar, .tar.gz, .tar.bz2, .tar.zst, .tar.xz, .tgz, .tbz2, .tzst, .txz. Support for password-encrypted archives is not available yet.

Redmond programmers added support for the aforementioned archive files thanks to the libarchive library, an open source project designed to develop a portable, efficient C library that can "read and write streaming archives" in a variety of formats. Libarchive supports additional archive types (Lzh, Xar) that could eventually come to Windows 11 as well.
