Hello again Mal,
while much of the QuizPort manual applies verbatim to the TaskChain module, the explanation of files requires some modification.
As you may have realized, files work differently in Moodle 2.x from Moodle 1.x. In Moodle 2.x, files are no longer associated with a "course", rather, they are connected with an "activity" or "resource". Thus, when you add a file in Moodle 2.x, you generally add it directly in the place where you wish to use it. i.e. within the activity or resource, and not in the "course". (also, see "Notes on files" below)
In TaskChain and HotPot activities in Moodle 2.x you add the files in the "Source file" area that is displayed when you add a TaskChain activity, or add/edit a TaskChain task. Put all the files you need for particular TaskChain in the "Source file" area. This means you put ALL the Hot Potatoes files and all the secondary files, such as images, audio and media players, that are to be used in the TaskChain.
If you have a lot of files, you may find it easier to zip up the files on your PC and upzip them in the "Source files" area of your TaskChain activity.
If you are using Moodle 2.3 or later, and your files are located in a central place, such as your "Private files" or an external "repository", then you can create an "alias" to the files from your TaskChain activity. The alias will ensure that changes made to the centrally located file are immediately available in the aliased copies of that file. However, as Philippe has pointed out, when backing up and restoring the Moodle 2.x courses, the alias of any file will be converted to a "hard copy" of the file that is detached from the original source file, and so does not reflect changes made to the original source. This has advantages and disadvantages, but in my opinion is not the optimal arrangement for most HotPot/TaskChain users.
But, I digress ...
When you have added all your files to the "Source file" area, choose one file as the "Main file" (click on the file and select "Main file"). Then you can scroll to the bottom of the page and click the "Save changes" button.
Hey presto - you've done it!
all the best
Notes on files:
- it is possible to set up a "Legacy course files" area on Moodle 2.x sites, which acts like the course files in Moodle 1.x
- you can share files between modules quite easily by putting the files in your private files area in Moodle 2.x and adding them as an "alias" (available only in Moodle 2.3 and later)
- you can also share files via an external "repository" (again you can add them as aliases in Moodle 2.3 or later), but you will need to work with your Moodle administrator to set one of those up
