The osmosis method is often better than trying to export and import because of the differences in the data structures between the two products. In terms of how Info Select works you will find many differences. For example, words don't wrap in the outline. This was done to insure that the outline shows an overview of as many items as possible. When you have more than one line of text, in Info Select you create a Note which is like a wordprocessing document.
Notes appear on the right side of the screen to the right of the outline.
Another difference is that Info Select does structured field data differently than Ecco. Fields do not appear in the outline. You can create databases and grids and forms on the right side next to the outline where Notes appear. There are more differences that you will discover but over time you will appreciate the power of Info Select. Making the transition will be well worth your effort.
