I was wondering if allow fragmentation is better or to not allow fragmentation. I'm new with computers and I don't really understand... Is it better to see long strands of blue or little strands of blue with red in between them since I used the allow fragmentation option??
Are you talking about the Defrag Freespace feature ? It will do a better job if you allow fragmentation ; however, your drive will be fragmented. My suggestion : Run it allowing fragmentation, and then defrag all the fragmented files.
