Ok since were on this topic I am pretty new to the Poser world and I agree with whats been said here. I have just started my seperate runtimes and have started renaming things so I have couple questions? 1. In the folders there are sometimes png files and rsr files can I delete the rsr files if there are pngs? 2. Some said something about things being compressed? Is it better to uncompress and what exactly is compressed? 3. I was told not to rename things in the Geometry and the Textures folder is this so?
