    Dynamic Data Exchange (DDE)* lets you create symbol tables and tickers in an Excel spreadsheet, which are dynamically updated.

    Hi, Cowboy ~

    I'm not sure this is the same 'DDE' to which you refer as this has nothing to do with Excel and is part of the 'Edit' window for the 'Open' action.

    It shows to be used with several different applications. I just used that one.

    Hi, Cowboy ~

    This 'DDE' is in the 'My Documents' > 'Tools' > 'Folder Options...' > 'File Types' tab > 'Advanced' button > 'Open' under 'Actions:'> 'Edit...' button for 'Editing action for type: XXX' in 'Edit File Type' window.

    Re: 'DDE' (XPP SP1)

    I unchecked 'DDE' for the hypertext transfer protocol to enable the opening of separate windows for each link within an OE e-mail since unchecking 'Reuse windows for launching shortcuts' in advanced IE Internet Options has no bearing.

    In what fashion does this impact the file type action, in this case 'open'?

    I don't know if this answers it for you--but DDE (dynamic data exchange) is a so-called "interprocess communications system" or IPC built into Mac, Windows, and OS2 OS's. It enables two running applications to share the same data. This is as Cowboy says, the means by which you can insert a spread sheet chart into a document created by a word processor like Excel into Word. Paint image to word would be another example. You could use an Excel macro to call MS Word and request the contents of a doc file; some applications use DDE to implement file association strategies--Word uses DDE in place of command line switches for example for added flexibility when the user needs to open or print a file.

    This is an old technology passed on from previous Windows versions. It has been supplanted by OLE which provides greater control over shared data. See Intro to DDE and Overviews of DDE and OLE and How They Are Used. You can run dde.exe from the command line. Check out dde in "Help and Support" and in your run box type "ddeshare" (no quotes) and read DDE Share's Help on "Using DDE Share" to context it.

    Hi, R2 ~

    I appreciate the info both you and SMDP have provided. Most of this I have crossed in searching, but so far the info is quite too general. How Windows opens files is as close as we have come.

    The purpose of this pursuit here, gentlemen, is the particular case of this post, in which discovery is sought in the use of 'DDE' in the context of file type actions and what unchecking 'Use DDE' exactly does in an effort to appropriately modify the behavior of OE's proper handling of hyperlinks.
