I was a bit surprised, this was made in India...the name sounds a little bit strange. There are many here that says good reviews bout this defragmenter and many uses it. I haven't tried yet this defragmenter, installed it already but in doubt coz there are some "precautionary" instructions on its help file manual. Unlike other defragmeneters I've already used paid and free, this is I think are the only one that has this kind of precautions. I have even read in one review on one site that when he uses the boot-time defrag he couldn't reboot his pc anymore and it mess up some of his file on his other pc. I uses AusLogic Disk Defrag free in the past and had no problem with it. How do compare it to Puran? What files and folders on the system should we exclude when using Puran? Any advice and suggestions on how to make this program more "safer" to use. I still have Windows XP SP3 Pro. Also, if there is a need to check all of this check box here.
