FAQ: KMZ for Borkou

Can I unzip a KMZ file?

Yes, KMZ is a regular ZIP archive. Rename to .zip and extract.

Is KMZ smaller than KML?

Yes, typically 5-10x smaller due to compression.

How do the contents of KMZ differ from KML?

They do not: it is the same document, only compressed. The layers, the tags in ExtendedData, the three-dimensional buildings and the WGS84 coordinates match completely.

Do all programs understand KMZ?

Google Earth, Google My Maps, QGIS and ArcGIS do. If some program only handles KML, rename the file to .zip, unpack it and feed it the doc.kml.

Can KMZ be edited by hand?

Yes: unpack the archive, fix doc.kml in a text editor — it is ordinary XML with styles and coordinates — and pack it back into ZIP, restoring the .kmz extension.
