I have several USB storage devices (from college, work, personal) all of which in one form or another may contain the same or similar folder and files. I am looking for a program where I can plug device 1 in and device 2 in tell it to compare the two and indicate the files and folders that are the same and/or different and then allow me to choose which to delete and/or keep. I know there is somthing like this out there but what Im looking for is one that will for example compare two MS word files or Adobe PDFs and even if there is a sentence or word that is different it will pick that up. Any advise? I'm not too worried about having to pay for this software. Thanks
