Excecuting CPIO in windows 2000 via DOS

I am currently trying to extract a cpio file from a Dos shell within windows 2000. This file is coming from a Unix environment.

The line I want to execute is
   cpio -icvBdmu < filename.cpio

I have downloaded an application called UnixDos which executes unix commands from within Windows 2000. However, this does not allow you to pass the switch B to the command CPIO. Therefore I could only use:

   cpio -icvdmu < filename.cpio

When executed the following erros message "Out of Phase -- reading next block" continuously repeats until I break out of it. The UnixDos does not seem to refer how you can set Block size to XXXX anywhere.

My question is does anyone know what is the best way to extract a cpio file in windows? Is it possible to pass the above switches?

Cygwin. Get it from http://www.cygwin.com
It includes, amongst many nifty features, cpio.
You will be able to use both -B and --block-size= syntax:-).

I have installed this application and have it working.

The only problem I am having is that the file I am trying to extract is over 1GB and the CPU usage maxed out.

I don't know if the "nice" utility have any effect under cygwin, but you could always try it:-).
r just live with it:-).
