    How can I associate a particular file extension with a particular Application? For example, I'd like all *.csv files to be opened by Excel, or I'd like all perl modules *.pm to be opened by TextEditor. Is this possible? I know you can right-click on a given file and use "open with" but how does one get it to apply to ALL files of the same extension?

    thanks in advance

    In Finder, get info (File menu or command-I) on a file with the extension. Then in the "Open with" section, choose the new application from the menu, and then click the "Change All" button.
