Database [Q] Path to Phone Memory

Hi.
I've got a C1604 and I realized its storage is splitted into two parts, one called Internal Storage, whose path is "/mnt/sdcard/", and another called Phone Memory. Since I want to link some of its files to sdcard, I've got to get there so I can give it a look. However, I couldn't find it. Does anyone know the path to there?

Thanks.

Ps.: Sorry for any mistakes, like many people here English isn't my first language.
