Hi MuraliP369,
That's what WM5Storage should do, allow any PC to see your Orbit as a card-reader, but you will have to disable activesync. But from what you've written, WM5Storage won't run on your Orbit...
There is a commercial offering called Card Export II by Softick, which is WM5 compliant from there website, you can find the software
here. The price is $14.95 + VAT....
