Changing the default directory of the file navigator.

I use pycharm-2017 3.3 community edition remotely from a server that has tons of users. 

Now every-time I try to navigate to a folder location either to open a project or select my python interpreter, the file navigation popup opens up and it freezes. It displays "/" location and my guess is that it is trying to look into each sub directory of "/" which has multiple terabytes of data, so it's freezing up.

Is there a way I can get it to stop opening "/" by default and open my personal directory?
