USMT2.UNC file not readable

I have a client who backed up all his files and settings using the files and settings Wizard in Win XP home onto an external HD. I backedup all his Outlook using a pst file. Well he restored his computer and then went to bring back his files using the wizard again as the new computer. The wizard will not recognize the folder (USMT2.UNC) I tried it on one of my computers and it wont work for me either. Inside the folder are 4 files they are STATUS and then 3 Dat files img00002.dat img00002.dat and img00003.dat. If the wizard can’t open them is rhere any other way I can get into them and retreive the data. The files ate 1.99GB 1.99GB and 1.78GB.

Thanks
