Our design templates are usually available for InDesign in the file formats INDD, IDML and INX. Check the compatibility notes to see which InDesign version you can use to edit which file format. As a rule, the following applies:

• INX files can be used with InDesign CS3.
• IDML files are the downwards compatible format and can be edited from InDesign CS4 onwards.
• INDD files are always the common format and can be used from the InDesign version with which they were created. You can find our information on this in the compatibility notes.

To find out which InDesign version you have, click on About InDesign... in the program under the Help menu.
