Note that each path should be separated by a colon. Remember to include the default paths when adding new paths (if you still want to include them).\

When you double-click a file and the application that starts up is not the application you intended to use to open that file, you can change the default application with the Inspector in the Workspace Manager. Select a document of the type for which you want to change its default application (e.g., "myFile.eps"). Choose Inspector from the Workspace Manager's Tools menu. From the pop-up menu at the top of the Inspector panel, choose Tools. The panel that is displayed shows all applications capable of opening that file. Select the application you want to use to open the file and click the OK button. Now, when you double-click a file of that type, it will start up that application. Of course, if you want to use another application to open that file, you can still first start up that application and open the file by choosing Open from its File menu (or equivalent).\
