I'm going to try and keep my request very specific to hopefully keep the discussion on track. Can someone provide an explanation on how disk space is related to Moodle 2.0's file handling? I'm hoping that someone can articulate why/how the following statement from Moodledocs is true :
"In Moodle 2.0, files are stored only once, saving disk space."
How does this (non-exponentially increasing disk usage) actually work when, from the teacher's perspective, files are copied from one resource to another (creating multiple copies of the same file) when they are used in multiple places?
Thanks to all for their hard work in explaining file handling - Looking forward to helping my teachers understand!
