How can I delete the contents of the IE5 History folder? I know that it is a 
Special Folder, so do you need to run this process as the system? If so how?

Answer:

This will get you the history folder and then maybe you can use the DeleteFile 
function to delete all the files in the directory.

1   uses
2     ShlObj;
3   
4   procedure TForm1.Button1Click(Sender: TObject);
5   const
6     CSIDL_HISTORY = $0022; {no need to define if using Delphi 5}
7   var
8     pidl: PItemIDList;
9     Path: array[0..MAX_PATH - 1] of char;
10  begin
11    {get location of history folder}
12    if SHGetSpecialFolderLocation(Self.Handle, CSIDL_HISTORY, pidl) = NOERROR then
13    begin
14      SHGetPathFromIDList(pidl, Path);
15      ShowMessage(Path);
16    end;
17  end;
