Software to restore File state...?

Hello,

Is there any software which can restore the file state to previous?

e.g; I’ve saved my document but I want to restore it to yesterdays state.

Please suggest.

Thanks…

I’m running Windows XP OS SP2

What OS are you running on?

Lot of software are available online which can restore your file state.
You just need to download and buy online.

Can u suggest me any of them?

Thnx
