I am sure that there is a software like that out there but it is not hard to do using simple windows tools. First figure out what kind of file are you most concerned about like pdf, or wmv or avi or jpg etc. Then right click my computer icon, click search and type the kind of file you are looking for. For example for image files type *.jpg For video files type *.avi,*.wmv,*.mpg etc whatever you have Then your whole computer will be searched for the kind of file and will show the results. There you can sort the files in alphapetical order and track any duplicate files. As easy as that. cheers
