I am not sure why but this file almost crashed My copy of Google Earth. I was able to deleat the file before any serious crash hit. I also have other files that are larger much larger and they were not on, but after I deleated this file, I turned on the files I had and Google Earth did just fine.
My machine is:
2.5GHz Pentinum
1.2GB Ram
256 MB Video Ram running a GeoForce 6600 LE Card from NVidia
I am on a Cable Modem at 4,000K Download 390k Upload.
