Understanding DFONT Issues
Frequent DFONT Opening Issues
Font Book Removed
When you double-click your DFONT file, you may see a dialog box from your operating system stating that it "Cannot Open This File Type". When this happens, it is commonly due to Font Book missing in %%os%%. You won't be able to double-click to open your DFONT because your OS doesn't know what to do with it.
Tip: If you don't have Font Book installed, and you know of another program to open your DFONT file, you can try opening it by selecting from the programs listed under "Show Apps".
Wrong Version of Font Book is Installed
In other instances, your Mac OS X Data Fork Font file version may not be supported by your version of Font Book. Visit the Apple website to download (or purchase) the latest version of Font Book. Your Mac OS X Data Fork Font file was probably created by a newer release of Font Book than what's currently installed your computer.
Tip: Sometimes you can get a clue about the version of DFONT file you have by right clicking on the file, then clicking on "Properties" (Windows) or "Get Info" (Mac OSX).
Summary: Not having the right Font Book version on your computer can cause problems opening DFONT files.

Assuming you have the right Font Book version installed, other problems can prevent you from opening DFONT files. If you're still experiencing problems opening DFONT files, there could be other computer problems. These other problems include (listed in order from most to least common):

- Past or present virus infection has affected your DFONT
- Device drivers for DFONT-related hardware are out-of-date
