Merlin's Delphi Forge

You shouldn’t have too much problem opening a Delphi 4 form in Delphi 2 but you won’t have luck opening a 32 bit or C++ Builder form in Delphi 1. The only way is to save the file in text form. Delphi 5 can do this automatically but in all the previous versions you have to do this all by yourself, form by form.
This is a full featured program that will do all the work for you. The source is dumped into Public Domain.

The standard MkDir() function can create only one directory, it can not create subdirectories at one time. This function allows you to create multiple directories (directories inside directories). Delphi 4+ have the ForceDirectories() routine which does the same thing. It is declared in the FileCtrl unit.

uses
  SysUtils, FileCtrl;
...
procedure MkDirMulti(sPath: string);
begin
  if sPath[Length(sPath)] = '' then
    sPath := Copy(sPath, 1, Length(sPath - 1));

  if (Length(sPath) < 3) or DirectoryExists(sPath) then
    Exit;

  MkDirMulti(SysUtils.ExtractFilePath(sPath));
  try
    MkDir(sPath);
  except
    { Handle errors }
  end;
end;

Example: MkDirMulti(‘C:Program FilesMy GameAudioSpeech’);
