Dev Drive is a new type of storage volume introduced in Windows 11, working with the Resilient File System (ReFS).Creating a Dev Drive involves creating a virtual disk, formatting it with ReFS, and then mounting it to a logical drive.Resizing a Dev Drive can be done using diskpart and does not require Hyper-V.When moving a VHD across machines, it is recommended to trust the Dev Drive again using the 'fsutil devdrv trust' command.
