Reference a common BookXRefs file

If you want to use a common BookXRefs file for multiple FrameMaker books, set the AltBookXRefsFile parameter to point to the common BookXRefs file. The common file can be referenced by a drive letter or a UNC path descriptor.
Note: You must use the front slash as a directory separator with the AltBookXRefsFile parameter. For more information, see Known Limitations.

AltBookXRefsFile=//servername/documentation/common/Group-BookXRefs.ini 
 
; the rest of the file can be empty and is ignored
