            This is an application-wide file where ENVI loads and saves preferences. To load or save preferences to a different location after the application has been launched, use ENVIPreferences::Load or ENVIPreferences::Save. To save an individual preference, use ENVIPreferenceItem::Save. To override this property throughout the application, set the PREFERENCE keyword of ENVI function when launching ENVI.
