A dialog box should appear asking you to select a directory and enter a file name. When you're done, click "Save".

You now have a choice over what layout the exported events should follow. There a four to choose from. When you click on one, it will be previewed in the text box on the right. Some of the layouts also give you the choice of the Date Format used. This can be selected with the drop down list at the bottom. When you're done, click "Next".

You will then be asked which dates and types of events you want to export. The date range options are pretty self explanatory. "A Month" includes every event in the next 30/31 days. So for example if it was the 12th of September, and you selected a month, you'd get the dates from the 12th of September to the 12th of October. "A Year" includes the events from today to the same date in a years time. And "Custom" allows you to select your own date range. Clicking on the down arrows next the dates opens a drop down calendar where you can make your selection. You can also choose which type of events you want to include in the export e.g. Weekly, Monthly etc.. When you're finished, click "Next".

Now just check the details are correct and click "Finish".

If the operation was successfully the following message should appear telling you how many events were exported.
