在哪里可以访问Gdx.files.local()?

I have a pre-made json file that I want to test out. This Json file will be modified so I want to read/write. I noticed that internal is read-only. So I want to save my Json file in the local storage(manually through eclipse or OS(windows 8)) such that I can access through files.local(). Does anyone know the address of the local storage defined by libgdx? So that I can save my pre-made Json file?I have a pre-made json file that I want to test
