Is there any point in using special software to copy files from a camcorder to a computer? I have a consumer-oriented Panasonic HDC-SD60 and have been using the supplied "HD Writer AE 2.6" software to copy files from it. If I forget to delete the files afterwards, record more footage and use the software again, it copies duplicates with '(1)' appended to the filename. Does anyone else use special software for this or does Windows File Explorer suffice? I'd like an option that recognises there are duplicate files and doesn't copy those again.
