I would suggest you google 'free defragging software' and you will find a program to do what you want. The program writer will tell you how to use it. However if you use the windows help and type defrag hard disk and read the responses then microoft would give you a solution. 2 programs I am aware are free are Auslogics Free Defrag and Smart Defrag. Put them into your search engine. Unless your PC is running slow then you shouldn't need to defrag. Unless you are a tidy person.
