Good or Bad?

Used Defraggler for the first time on an 88 GB drive that was 28% fragmented and using 50 GB. Result was 8% fragmented, 2 files (4 GB) fragmented, 351 fragments. I don't know how to judge how good the results were. I would have thought the ending fragmentation would have been significantly less than 8%. Thanks.

You to have two very large files.

Try this:

Go to Options > Defrag tab, and select "Move large files to end of drive".

Note that this process will take some time to complete.
