<p>I am using Team Foundation Server (TFS) for Visual Studio 2005.</p>

<p>Whenever i wish to compare two file's versions TFS displays a window with the differences.</p>

<p><strong>The problem is that it is always split vertically.</strong></p>

<p>In fact, almost every time, <strong>i would prefer to have it split horizontally.</strong>
I've already looked at TFS options and googled but i found nothing. I'm appalled to think that such option is not available!</p>

<p>Is there any way to configure TFS to split it horizontally?</p>

I've found the built in differencing tool in TFS woefully lacking so I set up WinMerge (
http://www.winmerge.org/
) in my environment in Tools -> Options -> Source COntrol -> Visual Studio Team Foundation.
A nice blog post exists below:
