Where to find SdFatInfo in Arduino 1.0?

Hello, I am doing my project now using Arduino Ethernet Shield..

According to this website Arduino Tutorials - Ethernet+SD ,
I have to modify SdFatInfo library in order to initialize micro sd card on ethernet shield.

But I can not find that SdFatInfo, the one that I find is only SdInfo...

Anyone can help me to find the SdFatInfo?

Thank you all...
