Digital Downloads complete address

[bsmither]

I've been experimenting with the digital download function and have noticed that when I click the link generated by CC, I am given the absolute complete path to the file.

For example (just an example, not for real), this shows in my browser's "Do you want to download this file" dialog box:

"D--Inetpub-wwwroot-store_digital-testdownloadfile.txt"

If the purpose of putting downloadable files in places outside the public accessible web space, why have the full path as part of the filename?
