Why do you need such software?

Well, when your add or install more and more softwares and files on your hard-drive, the system tries to look for space to store them, this it places them in different areas in your hard drive.  Once you run a program or open a file the operating system tries to assemble these file first and then open the program which mean slower performance. But when you Defragment your hard drive means that you are collecting all these files and placing them in one place for easy access.

Contig is a single-file defragmenter that attempts to make files contiguous on disk. Its perfect for quickly optimizing files that are continuously becoming fragmented, or that you want to ensure are in as few fragments as possible.

The cool thing about Contig is that you can choose to defragment the entire hard driver or just a single folder.
