File Links for email

I have a number of video type files (mpg, wmv, etc) loaded under a folder within my fully hosted web site and wish to make them available for download. I thought that I could just include the URL to the file in an email and then clicking it would automatically start the download process. However, I get “Internet Explorer cannot display the web page”.
I know the link is correct, I grabbed it off of an IE display of the index for that directory.
The URL I use is like this:


Don’t use upper case in a URL. Ever. Try making everything lower case, even the HTTP, and see if that works. This means you’ll have to rename (or create symbolic links) directories, perhaps some files, and use all lower case when you email the link.
