Can Storage Studio move Docker's data to my external drive?
Short answer: Not by moving its folder — Docker's data sits in an app container and would break whenever the drive is away. Use Docker Desktop's own disk image location setting to put it on another drive, and prune unused images and volumes in Docker.
Not by moving its folder. Docker's data lives in an app container on your Mac, and moving that behind a link would leave Docker broken whenever the drive is unplugged, so What's Using Space shows its size without offering a move.
Docker Desktop has its own setting for where its disk image lives, which is the supported way to put it on another drive; make sure the drive is always connected when Docker runs. Pruning unused images and volumes from Docker itself also frees a lot of space.
