MarkzTools is an XTension that can be used to prevent corrupted QuarkXPress documents, overcoming the dreaded bad file format [70], [39], and [108]. You can verify your saved Quark documents, so you will immediately know when the integrity of your file is suspect. Furthermore, using a special temp file
MarkzTools can try to help you recover documents that have become corrupted during a save operation while using Quark.
(*Note, this special temp file is only available to MarkzTools behind the scenes and is not selectable by the user.)In the case of a badly corrupted file in which the page layout data cannot be salvaged, the (scavenge text) feature may extract text stories from a document file.
MarkzTools alerts you whenever you are about to save a lower version document to a higher version. It also makes QuarkXPress backwards compatible, allowing you to open higher version Quark documents.
