Thank you for the clarification George. I haven't created any project .xpr files myself, so I don't really know where my transformation scenarios are stored. The only .xpr files I can find are:

• simpleLayoutSample.xpr
  
• sample.xpr

I found a copy of these files in c:\program files\oxygen XML editor14 and in c:\users\yves\my documents\oxygenxmleditor

Thanks
