For an Intranet web application (document management), I want to show a list of files associated with a certain customer. The resulting HTML is like this:

<a href="file:///server/share/dir/somefile.docx">somefile.docx</a>
<a href="file:///server/share/dir/someotherfile.pdf">somefile.pdf</a>
<a href="file:///server/share/dir/yetanotherfile.txt">yetanotherfile.txt</a>

This works fine. Unfortunetly, when clicking on a text file (or image file), Internet Explorer (and I guess most other browsers as well) insist on showing it in the browser instead of opening the file with the associated application (e.g. Notepad). In our case, this is undesired behavior, since it does not allow the user to edit the file.

Is there some workaround to this behavior (e.g. something like <a href="file:///..." open="external">)? I'm aware that this is a browser-specific thing, and an IE-only solution would be fine (it's an Intranet application after all).
