Default download Open/Save/Save As action for Internet Explorer by file type RRS feed

  • Question

  • We are trying to configure IE (Internet Explorer 9) on our user PCs so that, for a given file type "EXT", IE immediately opens the file without the user being prompted.

    After some investigation, I have added a registry key here:

        [HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\AttachmentExecute\{0002DF01-0000-0000-C000-000000000046}]
        "EXT"=hex(0):

    This works very well for all cases other than the very first time the user downloads a file of that type.

    Until the user has first manually clicked "Open" for a file of that type ("EXT", matching the value name in the registry key), file downloads of that type will just give the user a "Save As" dialog. Once the user has once selected "Open" (from the Downloads dialog in IE) for the first time for any file of the given type, all subsequent files with the same extension will just open as desired.

    Has anyone seen this before? If so, do you know a fix?

    Is there a flag in IE settings / registry akin to "ok-now-you-can-go-ahead-for-files-of-this-type"?
