Include any third-party Xtensions you have installed, such as Extensis’ QX-Tools. Some Xtensions, when used on a Quark document, are then necessary to open the document.

To do this, copy your entire XTensions folder (and XTensions Disabled for QuarkXPress 4 users) along with your other files.
Save your Quark files in whatever current version you are using. Our QuarkXPress templates are saved in version 3.x format, and Quark will not automatically save your layouts in a later format unless you specify this in the save dialog box.
We do not accept QuarkXPress Passport files. You must save your Passport documents without support for multiple languages.
