This menu item comes available when a project is selected in the tree view. It allows the Administrator to free up disk space by deleting document revisions and labels from the selected project. The revisions are marked for deletion and can be restored, but labels are removed permanently. To permanently delete the labels, run the Purge command. This action is not specific to ITP Admin.
