Defrag

I would like the opinion of some of you professional programmers. Would you consier Disk Defragmenter to be Batch or Real-Time processing? Please explain your answer. Kthx.

The process of defragging a disk is batch orientated. It is a process that you can leave running in the background, and not worry how long it takes.

Real-time is time seen from the users perspective, where system responses are expected to be as fast as possible.

Thank you very much.
