File storage in Moodle 2
4. A little bit technical...
When you add a file into Moodle, it is stored centrally.
If you upload file A to go into section A, you would do it in a very similar way to Moodle 1.
If you want to add file A into section B, you could go through exactly the same process again and upload it again. This means you are doing something you are familiar with Moodle. However, even if you manually upload the files twice, it is not stored twice. Moodle only keeps one of the files so that less space is used in Moodle. In the background, Moodle knows that this is the same file as used in section A so it will only keep one of them.
It works the same if you want to share file A in lots of courses. You can either upload it again OR you can go and find the file in Moodle to reuse it. You can only access resources from other courses in which you have editing rights.
It is not that easy to navigate to other courses in Moodle so the recent files option is usually the best. More on this later!
