# Freeing Disk Space Quickly

If PTY allocation or builds fail with “No space left on device”, try these steps (safe order):

1) Remove build/test artefacts:
```
DRY_RUN=1 scripts/devops/cleanup-workspace.sh   # preview
SAFE_ONLY=0 scripts/devops/cleanup-workspace.sh # include bin/obj if needed
```

2) Prune Docker cache (if allowed):
```
docker system prune -af
docker volume prune -f
```

3) Clear NuGet cache (local user):
```
rm -rf ~/.nuget/packages
```

4) Remove old CI artefacts:
- `ops/devops/artifacts/`
- `ops/devops/ci-110-runner/artifacts/`
- `ops/devops/sealed-mode-ci/artifacts/`
- `out/` directories

5) Re-run the blocked workflow.
