Nasty File Remover (or NFR), is a small and simple to use tool that scans system folder for driver files (such as nvidia, creative, ati etc etc) and presents the user with a list.
You can delete selected files / create a bat file to execute when and where you see fit and even create a standard zip file for backup.
This is handy when you are changing you'r current drivers and you wish to make sure that all previous driver files are removed.
Features version selection so you can select a single driver version's files.
Upgrading drivers (especially graphics and sound) can cause conflicts if files from older versions still exists. So using NFR after each driver installation is highly recommended.
