Aloha from Hawaii.

A search of the Community Discussion did not turn up an answer to do this fundamental question:

"What if any fatal flaws/benefits are there to running Disk Defragmenter, a basic system maintenance & performance utility that comes with Windows XP Pro (when it's being run as a guest)?"

My host system is a 24 inch iMac 2.8 GHz Intel Duo Core Extreme, 4 GB RAM, Mac OS Leopard v.10.5.5, 500 GB hard drive; VMware Fusion v.2.0, running Windows XP Pro SP3 as the guest system, with the guest drive allocated 80 GB, 2.3 GB RAM, and 1 virtual processor.

Everything is running fine, but as a general rule when natively running Windows XP Pro on a PC, after several software installations/removals, or simply over time, it's usually a helpful practice to run Disk Defragmenter to diagnose the status of fragmentation on the hard drive. Then, if necessary, it's beneficial to actually defragment the drive, using the same utility; i.e., Disk Defragmenter.

Please pardon my relative inexperience, but I'm just not sure whether this and other system utilities that come with Windows should still be used when running it in a virtualized environment, using VMware Fusion.

Thus, I'd appreciate any experienced replies to my introductory question, as well as the broader question of how it might apply to other system utilities that come loaded as components of Windows XP Pro.

Thank you very much, and looking forward to hearing from the experts that I know, who reside out there in the Community.

There are over 100 posts with the word defrag in them and I find it hard to believe you couldn't find something in at least a few to answer your question.

Here are 11 I made and I know some of what I wrote answers your question.

Defragmenting a sparse disk will cause it to grow, which is rather against the point of having a sparse disk. If you do this, you'll want to immediately follow up with Tools shrink (which requires not having snapshots). I would suggest not running automatic defragmenting on a sparse disk.
