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.

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
The rename file extension technique works like a charm in Windows 7. –  JohnnyO Nov 28 '13 at 16:53

No need for a third party tool. Change the extension to .zip, open and extract the file you want.

+1 If you are using 7zip, you do not even need to add a ".zip" extension. –  Aaron Oct 1 '14 at 17:09

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
@Abe solid state memory is the way to go. I have 16GB of RAM too, thats definitely helpful too. –  boulder_ruby Jun 4 '14 at 22:25
