File handling in Moodle 2.0
File handling http://docs.moodle.org/en/File_handling_2.0 new and improved in Moodle 2.0:
* 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.
* Duplicate files (for example, a large video file use in two different courses) are only stored once, saving disk space.
* 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.
