# Graph Force Clean and Sync
Perforce Helix4Git required. This option is used for Perforce Graph and Hybrid only. Removes all of the files in the workspace root, including the build history, and then force syncs the required files.

## Options:
You can select a number of options:
- **QUIET Perforce messages:** Enables the -q flag for all applicable Perforce Helix Core Server operations. Summary details will still be displayed.
- **Pin build at Perforce Label:** When a build is triggered by **Polling**, **Build Now** or an external action, the workspace will only sync to the Perforce label in this field. Any other specified change or label will be ignored.
Supports variable expansion, for example `${VAR}`. If *now* is used, or a variable that expands to *now*, the latest change is used (within the scope of the workspace view). For more information about environment variables, see [Variable Expansion](VARIABLEEXPANSION.md).
