I’m just curious. What disk Defragmenter/s are you presently using right now? Why you choose it instead of other disk defraggers? I have already tried several paid and free disk defragmenters in the past, some are good but some hugs my system and memory and they are very slow. Right now, I am using the JKDefrag v3.6…coz I found out that it is fast in defragging and optimizing my drives (default mode). My hard drives are getting faster and faster every time I used it. As my file system is FAT32, I know that it’s more prone to fragmentations than NTFS, so I have to use a fast defragger to maintain it in good shape. (My drives are less than 20Gig each, so FAT32 is a better option coz it’s faster). Another thing was that it’s very cute in size, and there is no set-up and installations, it runs with very low cpu and memory footprints…and no running services in the background when it’s not in use. Best of all, it’s an open freeware software program…wherein you can contribute your “secret techno” talents for its improvements. Its forum is very active and the author answers all questions and suggestions for the enhancements and improvements of this program.
