Change branch of GIT GUI

I was working with git and I don't know how this happened but by default I am seeing this as my master branc开发者_运维百科h "GIT Gui (C:/) C/" Can you help me in removing it to something else like C:/MyTestFolder .

After this guide on "Getting started with git gui on Windows":

The only way it could indicate another directory than C:/MyTestFolder is if your .git had somehow moved to C:/

So I would first check where that .git directory is right now.
