No Shared file in Network computers

Hi all, thanks for taking your time and readmy questions.
I recently just learnt how to File share with my 2 laptops(both Vista Basic)
i suceeded but one of my computers dosen't have a share file, but there is
only a Public folder. But in the other computer, there is a shared folder so
i can acess my other computer.

If you don't understand my question, please email me in cy_tan_97@xxxxxxxxxxx

Thank You Very Much.
