How to use:

First, KSP will only read the Mods in folder "GameData".

GDS will save the NAME of this folder in a file under this folder called "GameDataData.data", and add "_NAME" at back of the name of all non-default GameData folders, so they will not be read by KSP.

When a GameData set as the default GameData, GDS will remove the "_NAME" from the back of the selected folder name, and add "_NAME" back to the previous folder.

About create a new GameData, GDS will create a new folder call "GameData_NAME" under the game root folder, and create "GameDataData.data" file under this new folder. At last, it will copy the "Squad" folder form the default GameData folder.

About launch KSP part, the three argument will force KSP launch by using Direct3D 11, Direct3D 9 Or OpenGL, they can make your KSP use less memory.

If your system is in 32bit or you are playing a KSP version before 1.2.2, x64 option will be unavailable.
