I'm trying to link to a pdf following instructions here: http://www.coffeecup.com/help/articles/ … -designer/
But it isn't working.

I also made a mistake by using a capital letter in the name of my images folder, and now cannot seem to change it. Is it important that I change it?

In Resources, I find: "/(project folder)" -am I supposed to rename this?

How do I find this on my computer- I have my working file in my Documents, but the image file that I set up in Resources is nowhere to be found. Should these files be in my Documents, along with my working file?

Are there some instructions for getting the files set up (and how to locate them?) before beginning your site?

All you need to do there is locate the file on your computer that you want to include within RSD and create a link to. So say the file is called update.docx. Locate the file and include it under Resources. I recommend creating a folder there called "docs" and place all files in there. This way things are kept organized. Then when you want to create a link to the file, in any Href input box, just enter for the path docs/update.docx and that will create a link to the file.
