Where is the “File” link in the Administrative block?
The File Picker has replaced the Files option in the Administration Block of each course that existed in Moodle 1.9. Previously, if a file was used in different courses, it was duplicated. In Moodle 2, files are stored only once, saving disk space. As a result, there is no more course files space, access to a file is based on the resource or activity to which it is connected. Also, deleting a link to a file will delete the file, files cannot be deleted on their own.
