How do I get files and settings from XP FAST file (USMT2.UNC) into

Using XP's File and Settings Transfer (FST) wizard I created a file called
USMT2.UNC on an external hard drive. Now I want to transfer the files and
settings into Vista but Vista's Easy Transfer won't recognize it.

Unfortunately I cannot use Vista's Easy Transfer on the original computer
because the original computer's hard drive failed.

So all I have is this 6 month-old XP FAST file and I want to recover the
files and settings from it onto a new Vista laptop. But when I run the Vista
Easy Tranfer Wizard it won't recognize the USMT2.UNC file from the external
hard drive as a source for transfering the files and settings. The USMT2.UNC
file seems fine (not corrupted) and has a dozen or so .DAT files in is and a
status file.

How do I get my old files and settings from this file into Vista?

Thanks in advance.
