This site has some portable document format files (PDFs). In order to view these files you will need a program on your computer that reads this format. Adobe Reader, which reads PDFs, can be downloaded from Adobe's download page. Or, if you are unable to do this, you can use Adobe's online conversion tool which can be found on Adobe's Access Online Tools page.
You can customise how you view documents in Adobe Reader - see the User Personalisation of Adobe Reader pages on the TechDis website.
If you need to view a .doc file, but do not have the correct software, Microsoft Word Viewer can be downloaded from the Microsoft download page.
On certain pages there are movies which require the Flash plugin. If you do not have this plugin it can be downloaded free of charge from Adobe's Flash Player Download Centre. If you do not have Flash, or do not want to download it, you will see a static version of the initial image of the movie with a link to the other images used including any further content.
Some courses have links to YouTube videos. The EasyYouTube extension for Chrome or add on for Firefox provides an alternative viewing port for YouTube videos, with large buttons and fonts. You can add the URL of the video to the EasyYouTube homepage at http://www.yourvideofile.org/index.html to download the video, too.
The help documentation can be found at the Easy You Tube Help page.
