I've been messing around with .kmz files.
If I double click on the kmz file on my local hard drive, it opens in Google Earth as I'd expect and Right Click->Open With only has Google Earth in the options. So on my local hard drive, .kmz files are working great.
However, if I click on a link like this http://caiels.com/local/ivybridge.kmz. I get a dialogue showing a file name of ivybridge.zip and it tries to open in 'Compressed folders'.
Also if I link from http://maps.google.com/?q=http://caiels.com/local/ivybridge.kmz and click the 'view in Google Earth' option, it downloads as a zip file.
So I hope I'm asking this question in the correct place. Why does Explorer work fine with kmz, yet Internet Explorer treats them as a zip file? And is there anything I can put in the link to force it to download as .kmz and therefore open in Google Earth?
