How to include files in a folder using package & development wizard?

Anybody of u know how to include files in a folder using package & development wizard?

Problem:

I have package a VB project file into setup.exe & with their package files.

When i run the setup.exe, the default folder installation is shown as below:
c:\program files\Prjschool\

The files that i need (main.gif, mainlogo.gif & history.gif) is under
c:\program files\Prjschool\

instead of c:\program files\Prjschool\Data (where those files are originally under this folder in my real VB project file).

can anybody help me? thanks for ur generosity...
