Defrag as a Scheduled Task

If you are going to defrag use the console version it is more efficient not only that but you can add and create a Task to do it automatically every night.  I do this for all ym systems including friends and people I do side work for.  Defragging can be done often and is a way to make sure that your files are closer to each other.  When you are saving files, the file is not necessarily saved as an entire file or folder in a contiguous space. The files are saved in the first available space on a volume. After a large portion of the volume has been used for file and folder storage, most of the new files are saved in pieces across the volume. When you delete files or folders, the empty spaces left behind fill in randomly as you store new ones.

What I do is create a .BAT file with the following in it:
defrag c: -f-v

(note: create a separate line for each drive you want to defrag eg.. defrag d: -f-v)

Once you have the .BAT file you can create a scheduled task for it.
