Duplicate files can begin appearing in your system for a number of reasons, and can have a number of detrimental results aside from wasting your hard disk space. Various applications may install the same driver files, dll's, ocx's (activeX controls), etc. in numerous different locations on your system, or you may copy or download the same files into different folders on your system without knowing it. Sometimes the only result of this is waste of hard disk space, but most oftentimes, if there are a number of different copies of the same driver or other vital system file, your system may even crash or lock up sporadically causing loss of data or other disastrous results.
