1. Launch QuarkXPress 10
  2. Open a QuarkXPress 9.x project in QuarkXPress 10
  3. Make some changes to the project and select File > Save
  4. Without changing the name of project, click on Save.
  5. While saving, user does not get prompt 'File Name' already exists. Do you want to replace it ?


QuarkXPress 10 adds the extension '.qxp' to the project while saving whereas QuarkXPress 9 (or earlier versions) used to save QuarkXPress project without any extension.


To avoid files saving with the same name, Add the extension '.qxp' to the version 9 documents before opening them in version 10.
