current location - C:\Users\firem\AppData\Local\Docker\wsl\disk\docker_data.vhdx (53 GB), the Docker Desktop default because DataFolder is unset in C:\Users\firem\AppData\Roaming\Docker\settings-store.json
target - D:\docker\wsl (D: is labeled WSL and has 1.88 TB free, which looks like its intended purpose), X:\ works as an alternative
preferred path - once Docker Desktop runs again, set Settings > Resources > Advanced > Disk image location to the target and let Docker Desktop perform the move itself
manual path - quit Docker Desktop, run wsl --shutdown, add "DataFolder": "D:\docker\wsl" to settings-store.json, move the contents of AppData\Local\Docker\wsl to the target, start Docker Desktop
verify - docker info works, containers and images intact, then confirm the old vhdx is gone from C: and C: free space recovered ~53 GB
context - filed 2026-07-12 during a C: free-space debugging session, a top-level directory size scan of C: was still running when this was filed

C: on the desktop tower is at 7% free (32.7 GB of 464 GB) and docker_data.vhdx is the single biggest known consumer at 53 GB. Docker Desktop is currently broken and another agent owns that repair, so this agent filed the move as a follow-up instead of touching Docker config mid-repair. Whoever picks this up should coordinate with or land after the repair. * current location - C:\Users\firem\AppData\Local\Docker\wsl\disk\docker_data.vhdx (53 GB), the Docker Desktop default because DataFolder is unset in C:\Users\firem\AppData\Roaming\Docker\settings-store.json * target - D:\docker\wsl (D: is labeled WSL and has 1.88 TB free, which looks like its intended purpose), X:\ works as an alternative * preferred path - once Docker Desktop runs again, set Settings > Resources > Advanced > Disk image location to the target and let Docker Desktop perform the move itself * manual path - quit Docker Desktop, run wsl --shutdown, add "DataFolder": "D:\\docker\\wsl" to settings-store.json, move the contents of AppData\Local\Docker\wsl to the target, start Docker Desktop * verify - docker info works, containers and images intact, then confirm the old vhdx is gone from C: and C: free space recovered ~53 GB * context - filed 2026-07-12 during a C: free-space debugging session, a top-level directory size scan of C: was still running when this was filed
