Stream Explorer is a free tool that could be really useful to programmers or technicians who need to work with NTFS disc drives. It lets you view each of the physical sectors of those drives, in hexadecimal format.
Thus, thanks to Stream Explorer, you can see how each one of the sectors is and check its status. One of the most interesting features is that in Stream Explorer you can go through all the sectors that form each individual folder one by one.
Stream Explorer also tells you of the size and the content of each of those folders.
