Google Supercharges Blogger With Dynamic Views, ready to go? |
Ways to open and use files here
for *.jar files, need Java runtime https://java.com/en/download/for *.trz files, need Tracker https://www.cabrillo.edu/~dbrown/tracker/
for *.html files, which i assume are JavaScript models, just need a modern browser like Chrome.
