Thanks for your response. If new characters were downloaded in zip files, I would have no problems backing it up; but when I go to download my new purchases, whether character scenes or props, It always only offers an Install.RLD file that then loads the new items into the system. I never see a zip file. I do have the crazy talk itself backed up because it was downloaded in a zip file but none of the additional items that were purchase.
Once again thank for your helping.
PS: In looking further I think I found all my files at this location. Does this look right? I should backup this folder with and its subdirectories .? If my system was to crash, I could just reinstall crazy talk from its zip file and reinstalled this directory and its subdirectories.
C:\Users\Public\Documents\Reallusion
(this directory and its subdirectories)
