Deleting all files after uninstall using VS 2005 Setup project

[JM]

Hi Everybody,

I have created a setup project in Visual Studio .NET 2005. The setup is
for Windows application. It works fine but I am unable to do somethings
is this:

1. The setup uses couple of files and dlls. There are 2 files: one is
help.xml file and other is help.chm file. Both have same properties in
setup project. But after uninstall, help.chm file is removed from the
install directory but help.xml remains there.

I want help.xml also to be removed from the project. Is there something
I have to do for this?

2. My install package is copying some files to windows/system folder
also. But after uninstall, they are also not removed. I want to remove
them also during uninstall.

3. Install package creates the directory under Program Files. That
directory is also not deleted after uninstall. I want to remove that
also.

Any help would be greatly appreciated.

Thanks
JM
