this feature doesn't exist in coppermine's core code nor is it planned/scheduled for future versions. We don't believe in moving files around or renaming them. After all, the database keeps track of the files - the human doesn't have to. You (as coppermine admin) should FTP-upload plus batch-add anyway. Renaming the files before uploading them is strongly recommended. Bottom line: don't do stuff on the server that can be done easier, quicker or saver on the client. A webserver is mainly there to serve pages - making it do other stuff is usually not a good idea.
