Converting KMZ-file To KML
Answer : Yes. Inside the .kmz is a file called doc.kml , see wikipedia | Keyhole Markup Language | Structure You can use 7-zip to open the KMZ archive. References: KMZ Files | Recommended Directory Structure or change the file extension to .zip under windows to open with winzip. In unix/linux/osx: cp myfile.kmz myfile.zip unzip myfile.zip cp doc.xml myfile.kml No need for a third party tool. Change the extension to .zip, open and extract the file you want.
