Uploading Files
You may have existing content
that you want to add to your course, such as
web pages, audio files, video files, word documents,
or flash animations. Any type of file that exists
can be uploaded into your course and stored
on the server. While your files are on the server
you can move, rename, edit or delete them.
All of this is achieved through
the Site Files link in your Administration menu.

The Files section looks like this:

This interface is only available
to teachers - it is not accessible by students.
Individual files are made available to students
later on (at "Add Resources" - see
How to Create a Course).
As you can see in the screenshot,
files are listed together with subdirectories.
You can create any number of subdirectories
to organize your files and move your files from
one to the other.
Uploading files via the web
is currently restricted to one file at a time.
If you want to upload a lot of files at once
(for example a whole web site), it can be a
lot easier to use a zip program to compress
them into a single file, upload the zip file
and then unzip them again on the server (you
will see an "unzip" link next to zip archives).
To preview any file you have
uploaded just click on its name. Your web browser
will take care of either displaying it or downloading
it to your computer.
HTML and text files can be edited
in-place online. Other files will need to be
edited on your local computer and uploaded again.
if you upload a file with the same name as an
existing file it will automatically be overwritten.
If your content resides out
on the web then you don't need to upload the
files at all - you can link directly to them
from inside the course.
