Ok, a combination of emailing the post and bad editing made it a challenge to understand the question, so here goes again: I'm trying to open a "Save As" dialog so the user can choose a folder and type a file name, and the script will create a file with a bunch of information. The extension for this script-created file should be, say, .sse (an extension I've made up). Now, on Windows, you can use the following line in your script: myFile = File.saveDialog("Save Settings", "Super script extension:*.sse") That makes sure that whatever name the user types, the Save As dialog will automatically append the correct .sse extension. However, from the Adobe Scripting Guide documentation, it looks like the Mac ignores the "Supoer script extension:*.sse" part. So the question is: (1) On a Mac, how do you make sure that the file name the user creates in the saveDialog will have the correct extension? Thanks for any help or pointers in the right direction, Ariel
