Hello Sabine.
I use Web resources as a complement to the moodle online courses by linking them with URL´s. For example, I create a website for support of all my students, where I put lectures, programs, files, course assignments and so. I refer the students to this "repository" of information, instead of loading the files directly into the "course space". You can see an example of that in http://bartok.leon.uis.mx/str1 (Spanish only, 
at the moment).
Of course, if I need to upload a file within the course and the repository, I do that, so I will have two different sources with the same information. I think this coul help you.
Regards,
Jc.
