From time to time, we’ve been posting portable apps on this blog. Latest addition to this section is Google Earth 4.3, the popular virtual globe program from search giant Google. You can carry this version of Google Earth around in your flash drive or removable storage and run it from any computer without installation. Say you don’t have the necessary rights to install Google Earth at work, school or university - just run the portable edition. It’s just as good as the original!
P.S. – This is not Google Earth Pro or Google Earth Plus. Free edition but portable.
