I have been trying unsuccessfully to modify game files for World of Tanks Blitz, which is an app on the Windows 10 App Store. I heard from a fellow player that I need to make a partition on my hard drive and install the game on the partition, and doing so will allow me to modify the game files.

Problem is, I have no clue what a partition is, nor how to make one. Does anyone have a simple tutorial I can use to make this partition, and then how to install the Windows 10 app in that partition and how to set it up so I can modify the files?
