I have used auslogics and diskeeper 2008.

it has a nice grahpical interface, and is super small. exe you run and it defrags all hard drives on the computer automatically. This is open source and can be told to run as part of as screen saver or can be ran as a scheduled program in windows scheduler. Defraging is a must, it can cause your os to load slower as the hard drive takes time to find all the files for loading the os.Īs for a free excellent defragmenting program, I would suggest jkdefrag

But afte a big game install, app install or a new windows install. Now once those files are defragmented, then you don't necessarily have to defrag all the time. Games load slower thanks to hard drive piecing together the fragmented files. Especially while trying to use said program or app installed. I can guarentee you will see a performance hit before and after. If apps and files are installed and never fragmented. Also lets not forget after you install a service pack. Let's also not forget those who do anything with the large movie files. Even my $30,000 2 TB 10 SAS drive NAS running RAID 10 at work with 500,000 files on it and hundreds of users on them at any given time might only need it ever few months.Īnyone who installs games with 100's of small files and a few huge ones will see a huge problem with fragmentation. You shouldn’t need to defrag a PC more them once every 6 months unless you are doing hard core file swapping. Sure I ran it all the time in the old days.

Defrag is over rated in today’s world (NTFS and beyond).
