We have developed a small custom wep page within the CMS in which we are giving the user an option to Delete a file from a folder in CMS. I found there is a function for Deleting

UnifiedFile file = VirtualPathHandler.Instance.GetFile(path, true) as UnifiedFile;
file.Delete();

Do we have an option to check is there any reference for this file in any of the page? So that we can warn the user about this
