How do I rename basic templates in Storyline?

Hi, Yasmin - Please check out this information on Working with Templates, particularly the section on Renaming:

To keep your template library organized, you may need to rename or even delete templates from time to time. Go to the following directory on your computer:

%userprofile%\Documents\My Articulate Projects\Storyline Templates

Then rename or delete the *.storytemplate files found in the folder above.

Thanks Christie!

Sure thing, Yasmin! Always happy to help. :)
