I am running the bootcamp utility... and with just 5GB of drive i am trying to partition, it says that files can not be moved etc, and i cannot carry on with the process. and so i figure i should defragment to get the space all in one section of my harddrive (as is my understanding of defragmenting...). I am reasonably new to mac computers though... how can i do this? or any other solutions?! Thanks! Dane.
