Freeing up space · Caches and clutter

\n

Docker is taking up a huge amount of space — what can Storage Studio do?

\n

Short answer: Free Up Space can clear Docker's layer cache and Podman's build cache, and What's Using Space shows Docker's data size. For unused images and containers, Docker's own clean-up commands are the precise tool.
