Coincidentally, RAR support will be included in Windows 11: https://www.engadget.com/windows-11-finally-gets-native-rar-...
> We have added native support for additional archive formats, including tar, 7-zip, rar, gz and many others using the libarchive open-source project. You now can get improved performance of archive functionality during compression on Windows.
It doesn't mention unarchiving/decompressing, maybe I'm being nitpicky, but at a glance, it seems to only be about compression? That'd be horrible though, but more horrible changes that that have gone through lately so I guess you never know...
My worry is that this will just make drive-by malware easier.
(At least quickly thinking about it; I could easily have overlooked some complexity, but barring an unpatched libarchive exploit, I don't think this markedly increases attack surface...and at that point, you could probably make similar arguments about adding any new file format?)
Why is that?
