You can write custom code that will be executed on the according event via PowerShell.\ Let’s say you would like to fill or clear some properties on a lifecycle state change, automatically rename files when imported via drag&drop or prevent a lifecycle state transition when a combination of properties does not match your rules, etc.\ powerEvents makes it easy to create such logic in a simple PowerShell script.
