This tool cleans up temporary information created during a local edit by deleting the associated file from the workspace. The main action is to delete the associated file from the workspace.
If a file is temporarily edited in the context of an action, the tool "Cleanup Edit Session" is typically a component of the close action. If a persistent local file is created with the help of the tool "Create Persistent File", another action will usually be used (e.g. check-in) that contains the tool "Cleanup Edit Session".
