A dialog is displayed allowing you to choose the type of file you want to create. There will typically be various types of empty files.
When you click OK on that dialog, a file dialog will be displayed asking you to name the new file. Select the location and name of the new file. The file will then be created and opened in Packafied.
If an error occurs during this process, an error dialog will be displayed.
