The interface of IObit Smart Defrag is cool and really easy to use. I use IOBits Smart Derag program on all my PCs. I have never had any issues so far. This little light program works great on all the current windows operating systems keeping my discs defragged.
But yesterday when i clicked only C: disk to defrag, it selected all other disks. I've tried many times and still do not find out the real causes.
Before coming here for some help i've written a letter to IObit Online Support.
Have you encountered the same problem in windows 8?
