Diskeeper plans to introduce a file system filter driver later this year that will eliminate most file fragmentation before it actually occurs, company executives said Friday. ...

But the filter driver is designed to weed out about 75 percent of fragmentation before it ever occurs, by intercepting the data before it is written to the file system, and organizing it appropriately. ...

Materie said the technology was currently working through extensive testing, both to minimize the impact on CPU and memory performance, as well as file-system stability. On the latter metric, Materie said Diskeeper has found no problems. "It's absolutely bulletproof from a stability perspective," he said.
