Defragment... phone autocorrected it
I do understand. By the end of this you should understand a little more.
Ok, since windows is taking up a lot of your drive, let's add to that unallocated space. In gparted, the partition ending in n1p1, resize that partition by hitting the gear and choosing resize. In the new size box, drop the number to 350,000, that's 350 gb... more than enough for windows. You'll get a warning, hit yes.
Now you should have 544gb unallocated. Now we're going to move a few things.
Start with the next partition, which is the 500+mb efi partition. Hit the gear, and move. Try left clicking the partition, holding it, and drag it to the left till it stops (should be right against the windows partition, it may have a few mb gap which you won't be able to change).
If that doesn't work, you'll have to do it by numbers. If you wouldn't mind posting a screen shot of that dialog window, it would help. I don't move partitions often. Don't change any of the values if dragging it doesn't work.
You will have to reboot after this change and go back into the live image.

I could definitely use the extra disk space, Is moving your files to a seperate ntsf partition just like moving files to the D: drive in windows?
