Opening an .indt file from InDesign

Question

I'm trying to open a .indt file, when running the script from InDesign.
So far I've only been able to do so when running the script from the ExtendScript Toolkit with the following code:
var path="test/test.indt"
myFile = File (path);
myFile.execute();
However, when I run the script from InDesign, nothing happens. I've also tried the following version:
var path="test/test.indt"
myFile = File (path);
myFile.open();
This did not work either.
Please help me out.

Hi try the following code. It will work
var FilePath = Folder.decode(C:/Package/);  //where "C:/Package/" is the folder location
var FileName = File.decode(a.indd); //where a.indd is the indd file name
var fileLocation = FilePath + FileName;
app.open(File(fileLocation));
