+# 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.
