Inno Setup need foldername of app constant

For a specific setup, i need the foldername (without the path) of the {app} constant with a inno-setup script.

So if in the wizard for the 'Select destination folder' the next folder is selected: C:\ProgramFiles\MyAppFolder, i need 'MyAppFolder' in a variable to use in the setup script.

If you want just to get the tail of the {app} path, then you can call ExtractFileName function for the path with removed backslash. That returns tail of a given path. In the following script the PathTail var will contain the path tail unless the user selects a drive root (like e.g. C:\). In that case, the PathTail variable will be empty:

[Code]
function NextButtonClick(CurPageID: Integer): Boolean;
var
  PathTail: string;
begin
  Result := True;
  if CurPageID = wpSelectDir then
  begin
    PathTail := ExtractFileName(RemoveBackslashUnlessRoot(ExpandConstant('{app}')));
    MsgBox('PathTail: ' + PathTail, mbInformation, MB_OK);
  end;
end;

Just to be clear, here are examples of what you'll get:

User selected                          PathTail contains
----------------------------           ----------------------------
C:\                                    ''
C:\Program Files\AppFolder\            'AppFolder'
C:\Program Files\Subfolder\AppFolder\  'AppFolder'
