The freeware AllDup helps to keep the hard disk storage clean. As time goes by, a lot of files come along. Even photos take often lots of gigabytes of storage. Some of theses pictures are duplicates of others and a waste of storage. AllDup helps you to find these duplicates for deleting or moving. The nice userinterface is quite self explaning and offers a lot of selection options. AllDup is very fast on the search function and can also be taken on with you on a usb storage or sd card, because it's a portable, installation free program version.
