Deleted Files are still being defragged

I'm using Defraggler version 2.06.328 (64bit) and trying to defrag my computer because it has been running slow lately. 70 gigs of fragmented files. So i run defraggler for a few hours and when I come back its down to like 60 gigs and the scan is done. I checked the file list and the files that haven't been defragged are files of movies and other videos that I have recently moved off the hard drive and onto an external drive. However the computer is still reading them there, taking up a large amount of storage space and not allowing the system to be defragged correctly. the files all have the same path "C:\Windows\System32\wdi\{ffc42108-4acf-a4fc-8abdcc68ada4}\{d65ed0a0-2225-474f-bd78-9183cb78e5ae}\__________________. when i navigate here the folder is empty and when i right click in defraggler and click on "open containing folder" nothing happens. any help will be appreciated!

Alright so I ran WinDirStat and found that all the files I had moved onto my external were back. I deleted them and then erased my recycle bin. Finally after restarting the computer half a dozen times due to my switching between Windows and Ubuntu the files have finally quit showing up and I'm down to only 5 gigs of fragmented space. not sure how the files came back after I moved them but they're gone now so thanks for you help!
