Using Practice Files
Click on download files, this brings you to a new window and the frame on the left should display a link for 'practice files'
Click on this and the files will download as a zip (compressed) file (Files.zip).
Where ever you have your browser put the downloaded files (<CTRL>+J keycombination to show downloaded files in your Browser), you can double click the file
or on bottom of the chrome browser select open.
this opens the zip file in a windows explorer, you have an option to extract all files and store them on your PC.
Once this is done then you can navigate there and open the files..
You need the program that they were created with to use them, so if you're doing word or excel, you need those programs installed to use the files to practice what is shown in the tutorials
