Or how do you runn it if it is in a folder within your current app.exe folder?

Hello

  use shellapi to run the application, it will use the folder u r running ur program from as current folder and check about the file using FileExists

I hope that what are you looking for

Uses shellapi;

procedure TForm1.Button1Click(Sender: TObject);
begin
  if FileExists('test.exe') then
    ShellExecute(handle,'open','test.exe',nil,nil,SW_ShowNormal)
  else
    ShowMessage('This file is not exist in the current folder');
end;

Hello

  for better coding, use ExtractFilePath funcation tp get the folder for ur application that running.

uses shellapi;

procedure TForm1.Button1Click(Sender: TObject);
var
  Path : String;
begin
  Path := ExtractFilePath(Application.ExeName);
  if FileExists(Path + 'test.exe') then
    ShellExecute(handle,'open',Pchar(Path + 'test.exe'),nil,nil,SW_ShowNormal)
  else
    ShowMessage('This file is not exist in the current folder');
end;

if you want to run a program within ur current folder just add this folder to the path string like :

  Path := ExtractFilePath(Application.ExeName) + 'test folder\';

Best regards
