Hello Andrew - you can find a bunch of resources here:
Specifically the files are in this post:
There is also a great tutorial package here:
In addition to the sample data you find here in community - there is also data included in the tutorials found in help http://help.qlik.com/sense/en-US/online/index.html#TutorialsExamples.htm%3FTocPath%3D_____5
And if you ever need some quick data to test something you can go to the data load editor and press ctrl+0+0 you will get a test script.
So in your video "Quick Data Load" you up load a file called "salesdatamulti" or something similar. In your next video "Create your first chart" you start off by saying that you assume that the viewer has already downloaded the "Getting started" file which is available where the video is hosted. I cannot see anything downloadable on the page where the video is hosted except the desktop itself. The links you have provided are fine but they are not the same as those in the tutorial video. I wanted to follow it.
Thank you Andrew - I see the problem, I originally posted this video in a community documentQlik Sense Desktop - Creating Your First Visualization (video) with the sample data file attached. It seems the Qlik Sense Get Started | Qlik
page on the main web site - opens these videos separately, that was not my original intention, as visitors were supposed to be brought to the community pages, where they would see the additional information they may need. I will work with our web team to correct this.
