let us say you have N files in one directory and you rename the directory name. so for N files, u need to check destination side all M files and see if it is the renamed one. so you do NxM comparison and this is not scalable at all... > I hope that even in worst case when where are many large files with > the same size and mtime it will take relatively small time to perform > those additional steps.
