I have run defragger several times, but it always treats it as the first time, there are no past statistics to show it actually working.
This is despite reducing the initial 25% unfragged drive down by 2% t its current state.
I'm not sure what you are asking for?
Any defragmentation app will analyse the drive and report the current level fragmentation, and then reduce that fragmentation if you tell it to.
How fragmented your drive will get between defrags depends on how you are using your computer, ie. if you have saved/installed/updated something, if there has been a Windows update, etc.
If you want to keep a record of that then you could write it down, or take a screenshot, each time you analyse.
I'm not sure just how useful that would be for anything meaningful?
PS. There are 2 different things that are called 'Defragmenting' depending on what you are trying to achieve, Defraggler can do either one or a mixture of both depending on how you use it.
