“Windows 11’s last major update, 22H2 introduced native support for managing RAR archives, eliminating the need for third-party software,” writes Slashdot reader jjslash. “This enhancement is part of the OS’s broader capability improvements for handling various archive file formats.” TechSpot reports: 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.
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.
