Starting with Windows 10 preview build 20211, WSL 2 now includes a wsl –mount command that lets you mount ext4 and other Linux kernel supported filesystems, directly in installed WSL distributions.
This feature is especially useful for users who dual-boot Windows 10 and Linux and would like to access their Linux drives while using Windows.
