[AccessD] Memory hit

Suppose the following scenario:

1. I have a huge library of code, stored as classes or just functions and
procedures.
2. I drag this library into my current app.
3. 70% of the code in said library is un-used in said current app.

What is the cost in terms of physical disk size (can this be calculated?)
and in terms of RAM? If I call one function in a library that contains 30
functions, does Access load the one or all 30?
