    ## Docker-desktop on windows with WSL

    ### No free space on system drive
    Let's sat you got windows host with docker desktop and free space on `c:` suddenly disappear.
    Seeking lead you to `%LOCALAPPDATA%/Docker/wsl` where you see `*.vhxd` file of 32gb size. You can not find any relative
    settings in docker-desktop GUI (this is because WSL support is enabled btw), but you want this file to be moved to
    another disk, let's say `e:`

    ### move VHDX file to another disk

    Open command prompt, and there do

    ```
    wsl shutdown
    wsl --export docker-desktop-data e:\dockerdesktop\docker-desktop-data.tar
    wsl --unregister docker-desktop-data
    wsl --import docker-desktop-data E:\dockerdesktop\data\ e:\dockerdesktop\docker-desktop-data.tar --version 2
    ```

    Pay attention that no paths are starting or contain underscores or hyphens or dashes - wsl work really poorly with them and wsl's bash does even worse.
    After all command completed, restart docker desktop, delete `e:\dockerdesktop\docker-desktop-data.tar` you no longer need it.
