Thanks for this, Mixture, and for filing the report. I am not familiar with Applescript so have just had a play with it but it clearly needs a little more of my time to get my head around the commands and how they work on different applications, folders and files. I'll work at it this week. Thanks for the suggestion. There is an extra command on the Get Info pane. By holding down the Command key when clicking on 'Open with', the menu command changes to 'Always open with'. However, it still does not work!
