Doubt regarding Purge workflow and audit nodes on CQ 5.5
I read document at http://helpx.adobe.com/cq/kb/howtopurgewf.html to Purge workflow and audit nodes on CQ 5.5. It said that "You can start a purge manually by creating a file ./cleanWorkflow. Then, the watch service detects the file and starts a purge."
Could you please tell me where should i need create this file?
