Introduction - What is Defrag
You may need to defrag your computer hard drive after a few months of usage because the computers hard drive becomes fragmented causing the performance of the hard disk to dramatically decrease.

The disk defragmenter tool helps reduce fragmentation on the hard drives by organising the files physically in a line together this means the hard drive does not have to go as far when it spins to read it.
