On my system it lives in: /c/Users/moss/AppData/Local/Packages/CanonicalGroupLimited.UbuntuonWindows_79rhkp1fndgsc/LocalState/rootfs (Yuck.) There may be (probably is) a link somewhere. //wsl is probably some "magical" active link. By searching for ubuntu in the registry I found: Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Lxss\{d10ee784-05b0-4c00-be54-cba0d7e7a471} Its key BasePath has to path to that rootfs. I don;t know how stable that hex package id is, or whether it matters which Linux you've installed, etc. Also, I am running WSL 1, not WSL 2. I would think that WSL maintains a file somewhere with the information about distros and where they are, but I am not sure where that might be. A StakcOverflow posting said to look in: C:\Users\"yourusername">\AppData\Local\Packages\"xxxxx"\LocalState\root\fs The xxxxx varies by specific Linux distro/version. Naturally I would be careful *writing* anything down there, but I expect reading would be ok. HTH -- EM
