JetDrive - Version 2009 JetDrive is an easy to use disk optimization and defragmentation suite that can not only defrag a hard drive, but with a number of unique benefits and features to further improve a system’s efficiency.JetDrive can be set to run either manually or automatically according to the user’s preferences. As well as a highly effective defragmentation algorithm, JetDrive can also defragment the Windows Registry, resulting in a significant performance boost for most systems.If the user is short of time and needs a quick fix, JetDrive’s Fast Defrag will defragment the Windows core files only, resulting in as much as 90% of the performance boost in only five minutes.JetDrive can also check the hard drive for errors, and can optionally remove any garbage and temporary files before the defragmentation begins.
