What is KMZ file?

Files with the KMZ extension are used by a popular program – Google Earth, and they contain locations of maps shared within this software.

KMZ files are archives comprised of the main KML files (usually doc.kml) and potentially additional files, such as: custom skins, images, icons, or 3D models. All this content is packed using the ZIP method, which utilises a simple compression algorithm – DEFLATE – which provides higher compatibility with a large number of applications. According to convention, the doc.kml files are located in the main folder, and the additional files in sub-folders.

What elso do KMZ files contain?

KMZ files may include such data as:

  • markers for places with untypical names,
  • geographical coordinates – longitude and parallel,
  • 3D model data, with some restrictions.

Due to KMZ files, Google Earth enables bird’s-eye view display in many locations. Data contained in KMZ files can be displayed in any geo-spatial software supporting KML encoding.


KMZ files are also supported by Google Maps Online. It requires to upload a KMZ file on an FTP server and to paste the link into the Google Maps search box. Alternatively, user may do it manually, by placing a link directly into the following address:

Placing such link in a browser will enable to display content of a KMZ file.

What else may cause problems?

There can be more reasons which determine that you are not able to open the KMZ file (apart from the lack of the proper application installed).

First - the KMZ file may be incorrectly associated with the application installed to support it. In this case, you need to change this association by yourself. To do this, right-click on the KMZ file that you want to edit, click "Open with" and then select the program from the list that you have installed. After this operation, the problems with opening the KMZ file should be solved.

Second - the file you want to open can simply be damaged. Then, the best solution is to find a new version of given file, or download it again from the same source as before (maybe for some reason in the previous session the download of the KMZ file has not been completed and it cannot be opened properly).
