I've saved kml and kmz files in a file cabinet in the old Google Sites. I copy the permalink to these files and paste it into the search box on Google Maps to overlay the placemarks.
I've saved a test kml file in a folder on the new Google Drive, but I can't figure out how to get a permalink that I can paste in Google Maps. I found this link https://webapps.stackexchange.com/questions/26371/how-do-i-share-a-permalink-from-google-drive and used it to create this permalink https://docs.google.com/file/d/0B9sBXp66G86xWmlRbkZiYlRNdmc/edit?usp=sharing but Google Maps does not recognize it as a valid kml file. Do I need to change the URL?
Thanks.
For example, here is my html file
https://googledrive.com/host/0B1YPetHU8aMQMmtrcFB4eTMzd1E/kml_overlay.html
My KMZ file url would be
https://googledrive.com/host/0B1YPetHU8aMQMmtrcFB4eTMzd1E/kmz/river.kmz
If you would like to see the list of files, access the root level.
