Why not install your games on your D: or G: drive![]()
The free space must be adjacent to the partition that you want to grow. In this case, D:\ is in the way.
You could copy the contents of D:\ to G:\ ( 222 GB free? ),
remove D:\,
grow C:\ to desired size,
recreate D:\ in the remaining space,
copy back to D:\ from G:\
Windows 7 installs games on C: no matter what you do. Annoying.
There's things installed like steam/spotify etc. I assume these won't work after bein thrown around etc?
