Problem opening kmz files from IE

[DanielC]

Google has some sample kmz links on their web site (e.g. http://services.google.com/earth/kmz/GrandCanyon.kmz). If I click on the link, IE asks me to choose to open it (with Google Earth) or save the file as you'd expect.

I wanted to provide some kmz links on my own web site, but when I click the link to my kmz file (http://www.christinesbeachcottage.com/ct_virtual_tour.kmz), IE changes the extension from .kmz to .zip, and treats it as if it's a zip file. Even if I right-click on it & choose "Save Target as...", IE pops up with the dialog box asking where I want to save "ct_virtual_tour.zip" (Note: There is no file named ct_virtual_tour.zip on my site!).
The problem is not limited to my site, as I get the same problem when I click on links to kmz files on some forum sites.

This seems specific to my setup: Windows XP + SP2 running IE 6 with all updates. I don't get this problem when I test using my laptop running Windows 2000 with IE 6, or from my Linux setup running Firefox.

As a test, I copied Google's "GrandCanyon.kmz" file to my site, but again when I download it using IE, IE wants to open or save it as "GrandCanyon.zip".

Anyone seen a problem like this or has any ideas? How is it that my IE opens a kmz file correctly when it's on the Google site, but changes its extension to .zip when I open or download it from my site?

DanielC,

you need to configured your webserver to send the correct MIME types to the browser. More explanation is at the KML tutorial:

http://www.keyhole.com/kml/kml_tut.html

5 KML Server requirements
When responding to a request from the Google Earth client, a KML server must follow a certain set of rules so that the client can correctly interpret responses.

Upon success, the server must return a response code of HTTP 200 and set the response's content-type to a suitable MIME type.
Google Earth reads KML and KMZ files, and the MIME types for these are:
application/vnd.google-earth.kml+xml kml
application/vnd.google-earth.kmz kmz
The body of the response must contain valid KML data, including the xml declaration header (<?xml version="1.0" encoding="UTF-8"?>). If the server returns invalid KML, the Network Link will stop deactivate and output an error message.

Thanks very much

I used the "Mime Types" utility in CPanel to do this. It added the following lines to the .htaccess file in the same directory as my kmz file:

AddType application/vnd.google-earth.kml+xml kml
AddType application/vnd.google-earth.kmz kmz

Hi Daniel,

I have exact the same problem on my (dutch) site.

http://www.webkwestie.nl/google_earth_columbus/verwerking_02.htm

It's a educational site. When the student clicks on "KLIK HIER". He gets de zip-problem.

I see that there is a solution (?), but I don't understand how the problem is solved. Can you give me a example? I'm not a technical men, so if you can give me a simple explantion or example, I would be very happy.

Well technically a KMZ file IS a zip file, so its not doing that much wrong But don't you have a web master who can set the MIME types for you?

Hi Hulk,

I am just a simple webmaster.
Could you send a example of such a code?
Or could you refer to a webpage where a can study the html-code?

Greetings,

John, there are two options for Apache servers.

1. If you have root access find the mime.types file on your server and add two new lines:
application/vnd.google-earth.kml+xml kml
application/vnd.google-earth.kmz kmz

2. Or create a .htaccess file in the directory where your html files are stored and add two lines to .htaccess:

Hi there,

I added the code to .htaccess on my Apache server. It worked great for the .kmz file, but if I establish a hyperlink to a kml file, it simply displays the contents of the file:

<?xml version="1.0" encoding="UTF-8" ?>
