Suddenly lost 38GB of space after Defraggler Quick Defrag

Hello

After searching all day for a solution to the fact that I suddenly lost about 38 GB of free space on my D drive overnight I remembered I had used the Quick Defrag function of Defraggler late last night and came across discussion of this topic on this forum.

As my laptop is using Vista, the discussion is very relevant but , as there have been no recent posts on the old threads, I'm opening a new thread and hope this is OK.

I am not very knowledgeable about computers or the technical terms and unfortunately I'm no further forward in recovering what I've lost even after reading all the posts.

I tried deleting all my System Restore Points but this did not work.

Can one of the experts on the forum please advise what other action I can take or will the space suddenly re-appear as mysteriously as it disappeared ?

Please keep things simple as I'm a beginner with computers.

Thanks in advance for all help !!

I take it you must have followed the instruction in the link leading from item 2 here?
