3d Canvas 7 and TS2015

When I use the Trainworks plugin to export and go through the procedure, it tells me that the file has been exported to ...\Common\Railworks\Source\Developer\Addon\Track\. I can't find this folder anywhere.
Does anyone know how to select an export location that can actually be recognised, to makes things easier?
