I wish Comodo could develop a free defragment program. It seems that there is no such thing as a "free" defragment program. Computers continually get fragmented so it would boost the preformance of my computer alot. There are several commercial defraggers such as Diskeeper and PerfectDisk. Instead of security products, why not system utillites? It should include a boot-time defragmenter to defrag locked files such as the registery. And also a schelduer and different methods such as OO Defrag which has 4 defragment methods. I think one of the methods was complete-modified which organizes the files by the date of motified or something.
Hi and welcome! While your idea is a good one, I would simply like to touch on the statement you made that there is no such thing as a free defragment program, there are actually many out there including the one included in WindowsXP which honestly isn't that bad >for a windows utility
