On a computer:
To open the .zip folders downloaded from our website or store, in most operating systems all you need to do is to double-click on the .zip folder once it is on your desktop or hard drive.
In fact, some operating systems will automatically unzip the folder for you once download is complete. If not, then double-clicking on it will usually do, or right-clicking and choosing the unzip/extract option. Once the .zip folder has been unzipped (or "extracted"), you will find a new folder in the same location with the same name, containing the files you have purchased.
If the double-click or right-click solution does not work, then PC users can also get hold of a free trial of Winzip, a program that will unzip the folders for you. This is available here: http://www.winzip.com/
On an iPad/iPhone:
Please go to the app store on your iPad or iPhone and download a file manager app that handles zip files and pdfs (most will handle both these file types, and there are many free apps available that will do this).
Doing a search for 'zip' in the app store will show you options. Also, you can Google 'best zip app iPad/iPhone' to review the best, latest options.
Once you have an app installed on your iPad/iPhone that can handle zip files and pdf's, return to the zip file download page at Notes in Spanish, click on the zip file download link, and the app should automatically handle the rest.
