Fetch of NetworkLink Failed. Security violation.

[Usman_Rauf]

Hello !

I am using Google Earth pro. My requirement is to load the points data in realtime by using KML.

I am new to GE and after going through the examples, i am succeeded in loading multiple points through KML.

But when i try to update these points using <UPDATE> tag, i get the following error.

Fetch of NetworkLink "Update" failed (F:/GE Test/My Test/UpdateFile001.kml):
Security violation! Url F:/GE Test/UpdateFile001.kml cannot modify F:\GE Test\My Test\File.kml
Do you want to stop fetching, continue, or ignore fetch errors.

i have made 4 KML files.

1- originalKML.kml that is loading file.kml using <NetwordLink> from a local hard drive.
2- File.kml containing my desired points.
3- Update.kml that is loading UpdateFile001.kml using <NetworkLink> from a local hard drive.
4-UpdateFile001.kml containing updated longitude and latitude

I first run originalKML.kml and it successfully loads file.kml
but when i load update.kml to load UpdateFile001.kml, i get the error message shown above.

I have tried both absolute and relative paths in link elements.

The contents of the files are
