Note that Moodle administrators can refuse to change some of these settings as they can overload the server, so we may need to ask them to upload larger files for us. Multimedia files, especially videos, can be very large files, so we should have some preoccupation with the size of the files we upload. An alternative that we will explore in this book is to host our files on online services and then embed (a concept we will see in a moment) these in Moodle. This will save server space for our school or institution, but can raise other questions such as blocked websites, bandwidth, or e-safety that we will see in this book. Another alternative is to use file formats that have good size/quality ratios, and we will learn how to select and use such file formats later on.
