I made more than 10% space on disk, yet defraggmenting is still buggy. File defraggmentation is stuck like on 10% or 46%. I am positive it is not open. As it is tv show, don't know why would it be open. Previously i thought it doesn't work because i didn't have enough space on disk, but now i have no idea. Previously similar file defraggmented in minute and now it is taking 30 minutes, it is 100% stuck.
