Maybe your device which is running KA Lite simply does not have enough diskspace to store all the Khan Academy content available. What can you do? It’s simply a matter of changing where KA Lite finds your content if it is stored on an external drive, such as an SD card.
You will need to edit the settings.py file and point to wherever you have stored your content, as opposed to the default settings of the content folder in the .kalite subdirectory. For more information, read more about Configuration Settings in our FAQ.
