Here's a simple way to get to the folder where the files are extracted to at Runtime. You need to add a Static method from the OpenSpan.Runtime.Core.dll to get the GetProjectPath method (right-click in the Toolbox and select Choose Items, then select the Pega Robotics Static Members tab  and select From Directory Location). If you are using an older version of Studio without the FileUtils, you can use the Static method from the GAC Path.GetDirectoryName (right-click in the Toolbox and select Choose Items, then select the Pega Robotics Static Members tab  and select From Global Assembly Cache, select the mscorlib assembly and locate the method).
