Defraggler hangs when set to move large files to end of drive

[Paul Smith]

Defraggler 1.15.163 hangs when I set it to move files larger than 1000MB to the end of the drive. It stays at 1% for 20+ hours with no hard disk activity consuming 50% CPU. I can't even stop the defrag from Defraggler. I have to end Defraggler.exe task in Task Manager.

 

However, Defraggler screams when I disable the option to move large files to the end of the drive and finishes in reasonable time. However, I would like to move some ZIP and other files larger than 1000MB to the end of the drive.

 

I get the same issue when running Defraggler GUI or command line df.exe C: /Large *.* 1000M.

 

I should mention that this is my corporate laptop running Pointsec for drive encryption. Not sure if that matters or not.
