I always play it safe from the start, and organize things my own way. 1.) I download all my files into a download folder. 2.) I create a folder for catgories such as props, etc. 3.) Each item gets a folder for the zip file. 4.) I create "undone" folder where I unzip each file 5.) I look at the readme file, and the folder structure of the download. 6.) I install from there. (drag and drop, or copy). That's the way that works best for me. Not every artist puts their work in the appropriate folders. Not every artist does everything the same way. We can thank them for their creations, and take care of organizing ourselves.
