I have recently installed Zen-Cart and am slowly exploring its features. For me this is made a little more confusing by what appear to be quite a lot of superflouous files that I do not remember loading, nor want. These are files in the 'images' folder such a 'bugs_life', manufacturer references to companies such as 'Matrox' and 'extras' in the admin menu relating to Media files' 'Record Artists', 'Music Genre', 'Media Manager' etc

Is there a list somewhere that tells me what I can safely delete and get the site pared to essentials and my own files?
