Question

Wiki engines

How to organize an online library of usefulness.
We have two types of usefulness:
1. Links to articles / videos
2. Files: books, presentations, videos (they are large).
And if with the first - more or less everything is clear (the same wiki). That's how to organize the second - is not entirely clear.
I will listen to your options, ideas and suggestions. Share your experience.
Thank you!
