Randy/Roberto, Microsoft used to say that disks using the NTFS file system didn't get fragmented - However, like most of Microsoft's statements it was wishful thinking. Several after-market 'defrag' programs appeared to take care of this for NT3.51 and NT4. With NT5 (Win2000), Microsoft admitted that NTFS did indeed get fragment and included a disk defragmenter program with it. But, you're still better off getting an aftermarket program to defrag Win files.....
