File handling
From MoodleDocs
Template:Moodle 2.0The way files are handled in Moodle has been changed significantly in Moodle 2.0.
- Previously, if a file was used in different courses, it was duplicated. In Moodle 2.0, files are stored only once, saving disk space.
- Full support for Unicode file names on all operating systems.
- Metadata about each file (author, date, license, etc) and what the file is used for are stored in the database.
- Files are no longer just "uploaded to the course". Files are connected to the particular bit of Moodle content that uses them. (For example, a file may belong to a file resource, a forum post or a wiki page). Access to these files is then controlled by the same rules as as that bit of Moodle, increasing security.
