Windows

I hear what you're saying, cause it pisses me off too (I use primarily Diskkeeper) but isn't the difference between kind of tight and tight just hundredths of milliseconds and aren't there other areas to help improve performance that would be better to focus on?

i believe the windows disk defragmenter will not defrag free space, while some of the commercial specialzied defragmenting utilities do that.

This is one of those really irritating issues with me... I expect Microsoft to do this type of thing. I think they figure it makes it more difficult for people to resize their partitions and put Unix on the unused part. But then I downloaded the Auslogic defragger, and it left the same little sliver of files way up at the end of the partition. It seems to me that defrag means contiguous and packed tight!

PS:I released the first commercial defrag utility for MS-DOS in 1985. It was called 'Filemax'. Unfortunately, the UI sucked, and it never caught on! :>

If that were done, it would be guaranteed that each and every file whose size increased beyond the no. of clusters currently allocated would of necessity become fragmented. "Intelligent" defragmenting programs attempt to place and disperse files so as to leave growing room for those most likely to need such.
