http://blogs.msdn.com/b/brian_jones/archive/2005/07/14/438841.aspxGoing into the announcement about the new formats last month there was just a ton of content that had to be reviewed. There were a couple of whitepapers, an FAQ, the press release, etc. I actually thought I'd done a pretty good job of reviewing the stuffen-USTelligent Evolution Platform Developer Build (Build: 5.6.50428.7875)http://blogs.msdn.com/b/brian_jones/archive/2005/07/14/438841.aspx#439294Fri, 15 Jul 2005 18:33:33 GMT91d46819-8472-40ad-a661-2c78acb4018c:439294I'm Brian JonesAndrew, there are a couple of options for applications that already support the existing binary formats (I think that's what your question was about). Office 12 will of course continue to support the existing binary formats (.doc, .xls, .ppt), they just won't be the default format anymore. <br>The new XML formats will be significantly easier to work with, and should be viewed as a positive by anyone that wants to build tools that work with the Office formats. We made the announcement about the formats so early in the project cycle so that folks could be prepared. If they want to support the new formats, then they will need to do some work. Otherwise they can continue to use just the binary formats. <br> <br>-Brian<div style="clear:both;"></div><img src="http://blogs.msdn.com/aggbug.aspx?PostID=439294" width="1" height="1">http://blogs.msdn.com/b/brian_jones/archive/2005/07/14/438841.aspx#438875Thu, 14 Jul 2005 21:04:26 GMT91d46819-8472-40ad-a661-2c78acb4018c:438875AndrewI have a question about these new formats as far as other app compact for example Adobe Acrobat. At the current moment you could not use the current office 12 formats and drop them on Acrobat distiller and have them convert to PDF format. How does MS plan to keep things working with older version of these types of applications ?<div style="clear:both;"></div><img src="http://blogs.msdn.com/aggbug.aspx?PostID=438875" width="1" height="1">
