Managing Folder Files

I wanted to manage the files in Daz3D folder I set. I have one folder in the Content Library for downloaded models and another for Daz current files like Essentials. I wanted to know what those folders are for cuz there's a ton of assets, 4k textures and such I don't need, afraid if I simply go out deleting stuff will break the models since Daz is not in my C drive and it requires you to run the program in a non admin user.

This is what the default folder looks like atm.
