# OrbStack data This folder is used to store all OrbStack data, including Docker images, containers, and Linux machines. If you see an 8 TB data.img file, don't panic! It's a special type of file that it only takes as much space as you use, and automatically shrinks when you delete data. It does *not* take up 8 TB of disk space. To find the real size: - Run "du -sh data.img" in Terminal, or - Right-click the file and select "Get Info" Then look at "size on disk" For more details, see https://orbsta.cc/data-img
