<DRIVERFILE> for bcm43xx-fwcutter

In bcm43xx-fwcutter tool README.fedora, I read:

   Having obtained the file from which you wish to extract the firmware,
   run this command as root. Replace '<DRIVERFILE>' with the actual name
   of the file, of course:

      bcm43xx-fwcutter -w /lib/firmware <DRIVERFILE>

Now in my WinXP partition, in the directory:
   C:\Program Files\Broadcom\Broadcom 802.11\Driver
I find the files:
   BCM43XX64.CAT
   BCM43XX.CAT
   BCMWL564.SYS
   bcmwl5.inf
   BCMWL5.SYS
   bcmwls32.exe
   bcmwls.ini
   bcmwlu00.exe
   uninstall.log

Am I on the right track?  Which is the <DRIVERFILE> ?
I suspect I may have to use several of these?  Is
this true?  How?

Thanks for your help.
Mike.
