newbie question
I am working with a content management system. Since I am pretty proficient with HTML and style sheets I asked the developer if I could have access to the orginal templates and files so I could modify it for specific purposes. He sent me all the files and I opened them in Dreamweaver hoping I could edit them there. I open the .aspx and .vb files but don't see anything there that looks remotely like I could work with. I am attaching a screenshot of a partial menu of files. Is it possible to work with these files and if so where do I start?
