Recovering deleted files from a memory card?

Hello,

Anyone know how to recover some files from a sub folder on a memory card, in Windows 2000 or XP Home?
Will I need a utility? If so, anyone know of a good free one, that is spyware free?

Please help.

I didn't find the right solution from the Internet.
