There's no need to defrag if all you've done is an install. Defrag only
becomes significant if you have deleted files, creating odd-sized spaces
on
disk, then added more files. There's some deletion that goes on during an
install, but not enough to be concerned about.

But, I have filled 14GB already, and probably will do more. Especially as
I'm looking into video-editing. :-)

OTOH, if the drive isn't fragmented and there isn't any application usage
history then defragging won't do anything, and it will complete very
quickly. I would always recommend doing Scandisk before defragging.

How do I tell whether it's fragmented or not? I use my hard drive A Lot.

The reported amount of disk space used does not indicate anything about
the
fragmentation on the drive.

But won't space used affect largely the time it takes?

Thanx for your help,
