(Information and examples taken from the DroidScript documentation)
The GetExternalFolder method returns the full path of the external storage (in early versions of Android, this is often a removable sdcard).
In some phones(e.g my phone) it returns the full path of the internal storage.
app.GetExternalFolder();
function OnStart() { fldr = app.GetExternalFolder(); app.ShowPopup( fldr ); }
