From what I theorized, this changes flow of traffic in the Bus for RAM, GPU, CPU, HARD DISK. By creating a new Path.
That comment doesn't make any sense - all you're doing is moving your swap file to a different partition, and the only beneft of doing that is that it will be contiguous, which can improve performance if it's on a spinning hard disk. Also, those steps are serious overkill - if that's all you really want to do, you can temporarily turn swap
off, defragment your disk (you might need a 3rd-party tool, since I don't know if the builtin defrag is thorough enough), then turn swap back on with a suitably large size.
If you're suffering from poor performance due to excess swap activity, a much better solution would be to make more RAM available to the applications you're trying to run. Close your other memory-hungry apps (like your web browser) and your games will thank you, and if your motherboard is capable of supporting more RAM, max it out.
Probably the best solution, though, is to get an SSD and put your operating system on it. Your computer will probably boot in under 30 seconds, and
everything will be faster.
Create Dynamic Disk
...
Now once you created dynamic disk; Shrink Volume and create a new partition of 20gb (1024* 20)=20480
You don't actually need to do this - Windows 7 (and later) can shrink Basic disks just fine.
