Background: If this alert message displays, it means that the link in the Mac OS Desktop file between QuarkXPress and its documents has been damaged or does not exist. To repair the link, you need to rebuild the Desktop file on your Mac OS computer. To do this, see the section ”Rebuilding the Desktop File“ below.

Another symptom of this problem that you might encounter is a “generic” icon for the QuarkXPress document. On the Mac OS, a generic icon looks like a blank page with a folded top-right corner.


“Generic” Icons

The Mac OS maintains an invisible database that stores the pictures of the customized icons for every kind of file on your hard drive. This same database also stores information about what kinds of files are on your hard drive, and which application creates which kind of data file. This invisible database is referred to as the “Desktop file.” Normally, QuarkXPress document icons are customized to tell you by looking at them that the file is a QuarkXPress document. If the icon appears to be “generic” (looks like a blank page with a folded top-right corner), it means that the file is no longer associated with the QuarkXPress application in the Mac OS Desktop file. If the document can be opened by choosing File > Open within QuarkXPress and no alert displays, then the Desktop file is most likely damaged and needs to be rebuilt.


Rebuilding the Desktop File

Rebuilding the Desktop File is a periodic maintenance procedure that Apple recommends for all versions of the Mac OS.

The procedure for rebuilding the Desktop file varies with different versions of the Mac OS. If you don’t have Web access to obtain a copy of this article, here’s a desktop rebuilding procedure that will work with many Mac hardware/OS combinations:

  1. Restart the computer.

  2. As soon as you hear the restart chime, press Command and Option, and press them until you see the message “Are you sure you want to rebuild the desktop file for [name of your hard drive]?”

  3. When this message displays, release the Command and Option keys, and click the Yes button. The desktop file should now commence rebuilding. The procedure might take several minutes, depending on the size of your hard drive.

This Desktop file rebuilding routine incorporated into the Mac OS repairs, restructures and compacts the existing Desktop file. Occasionally, this may not be enough to repair all the damage. If symptoms of a damaged Desktop file persist after you rebuild the Desktop file, it may be necessary to completely delete the old Desktop file, which forces the Finder to build a new one from scratch. This procedure can be performed with one of several utility programs, such as Norton Utilities, TechTool Pro, MacTools, or ResEdit.
