When will the Smart Defrag Pro be updated? As a paid customer, it would be nice not to have to wait for features that users of the free version already have.

Hi roger_m,


You may have noticed that in the past, IObit had released the smilar SD Pro version about 2 weeks later than the Free version had released.

I suppose, this is to ensure that not only the new suggestions to be implemented but all the bugs (if they exist) to be corrected in the new version of Free before the new similar version of Pro is released.
