I have a kmz file. Is there an easy way to convert it to KML? Can I just "unzip"?

Yes. Inside the .kmz is a file called doc.kml. You can use 7-zip to open the kmz archive.

This is most likely no practical solution, but you can import your kmz-file in google earth (open) and export it (rightlick -> save) it as kml. Somehere out there is certainly a easy tool for conversion/extraction.

good idea Google Earth choked on a 57MB file. I guess that is a different problem. – Abe Nov 12 '12 at 22:19

hui, then maybe you should first extract the doc.kml file as mentioned by HeyOverThere. On this link you will find further informations about the kmz file format: developers.google.com/kml/documentation/kmzarchives – Curlew Nov 12 '12 at 22:26

or change the file extension to .zip under windows to open with winzip.

In unix:

cp myfile.kmz myfile.zip
unzip myfile.zip
cp doc.xml myfile.kml

You can just unzip the kmz file directly, Unix doesn't care about file extensions. – HeyOverThere Nov 12 '12 at 23:26
@HeyOverThere most Unix utilities don't care, but some, such as gunzip are picky about extensions. – scw Nov 13 '12 at 2:55
