Here's what I have:

The user supplies a directory, usrDir.

There may be anywhere from none to thousands of files in that directory. I want to copy everything that is in there to progDir.  How do I do this?

I wrote myself long time ago a program to copy a folder. It can copy also subdirectories inside the directory you want to copy.

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,
  StdCtrls, FindFile, Filectrl, ShellApi, ExtCtrls;

type
  TForm1 = class(TForm)
    Label1: TLabel;
    Edit1: TEdit;
    Label2: TLabel;
    Edit2: TEdit;
    CheckBox1: TCheckBox;
    CheckBox2: TCheckBox;
    Button1: TButton;
    Button2: TButton;
    FindFile1: TFindFile;
    Image1: TImage;
    Image2: TImage;
    ListBox1: TListBox;
    procedure Button2Click(Sender: TObject);
    procedure Button1Click(Sender: TObject);
    procedure Image1Click(Sender: TObject);
    procedure Image2Click(Sender: TObject);
    procedure FormCreate(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1 : TForm1;
  Path,
  Path2 : string;

implementation

{$R *.DFM}


procedure CopyRecursive(srcDir, dstDir: string);

var
    cmd : string;    
begin
  cmd:='/c xcopy '+srcDir+' '+dstDir+' /E';
  ShellExecute(Application.handle,'open','command',PChar(cmd),nil,SW_SHOW);
end;

procedure TForm1.Button2Click(Sender: TObject);

var
    Salida  : TextFile;
    AppPath : string;
begin
  AppPath := ExtractFilePath(Application.ExeName);
  AssignFile(Salida,AppPath+'\'+'Copia.ini');
  Rewrite(Salida);
  Writeln(Salida,Path);
  Writeln(Salida,Path2);
  CloseFile(Salida);
  Application.Terminate;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
  if ((Path='') or (Path2='')) then
  begin
    ShowMessage('Error... No hay directorio Source/Target');
//no source directory
  end
  else
  begin
    Path := Edit1.Text;
    Path2 := Edit2.Text;
    if FileExists(Path2) then CopyRecursive(Path,Path2)
    else
    begin
      MkDir(Path2);
      CopyRecursive(Path,Path2);
    end;
  end;
end;

procedure TForm1.Image1Click(Sender: TObject);
begin
  Path := ExtractFilePath(Application.ExeName);
  SelectDirectory(Path, [sdAllowCreate,sdPerformCreate,sdPrompt],1000);
  FindFile1.Path := Path;
  ListBox1.Items := FindFile1.SearchForFiles;
  Form1.Edit1.text := Path;
end;

procedure TForm1.Image2Click(Sender: TObject);
begin
  Path2 := ExtractFilePath(Application.ExeName);
  SelectDirectory(Path2, [sdAllowCreate,sdPerformCreate,sdPrompt],1000);
  FindFile1.Path := Path2;
  ListBox1.Items := FindFile1.SearchForFiles;
  Form1.Edit2.text := Path2;
end;

procedure TForm1.FormCreate(Sender: TObject);

var
    Entrada  : TextFile;
    AppPath  : string;
    InpSt,
    OutSt    : string;
begin
  AppPath := ExtractFilePath(Application.ExeName);
  if FileExists(AppPath+'\'+'Copia.ini') then
  begin
    AssignFile(Entrada, AppPath+'\'+'Copia.ini');
    reset(Entrada);
    readln(Entrada, InpSt);
    readln(Entrada, OutSt);
    Edit1.Text := InpSt;
    Edit2.Text := OutSt;
    Path := InpSt;
    Path2 := OutSt;
    CloseFile(Entrada);
  end
  else
  begin
    Edit1.Text := '';
    Edit2.Text := '';
    Path := '';
    Path2 := '';
  end;
end;

end.

Hi,

Another version:

uses ShellApi;

// copy a directory tree
procedure CopyDir(FromDir, ToDir : string);
var
 FOS :tSHFileOpStruct;
begin
  FromDir := Trim(FromDir);
  if FromDir[Length(FromDir)] <> '\' then FromDir := FromDir + '\';
  ToDir := Trim(ToDir);
  with FOS do
  begin
    Wnd := Application.Handle;
    wFunc := FO_COPY;
    pFrom := PChar(FromDir + '*.*' + #0);
    pTo := PChar(ToDir + #0);
    fFlags := FOF_ALLOWUNDO or FOF_MULTIDESTFILES or FOF_NOCONFIRMMKDIR;
  end;
  SHFileOperation(FOS);
end;

// usage:
procedure TForm1.Button1Click(Sender: TObject);
begin
  CopyDir('c:\tools','d:\tools');
end;

Regards, Geo

that is really strange

i get no help for the tSHFileOpStruct.

but it compiles without an error so the compiler knows that data structure.

how or where do you access help on that structure?
(i looked in the sdk help but found nothing)

thanks for answering so fast

how do you find this kind of information?
i mean if the help system doesn't tell me how am
i supposed to use this command?

and what about the other (thousands?) useful commands
that do exist and i do not use because the help doesn't
do what it is supposed to do?
is it necessary to read alle the microsoft knowledge
base articles to get this kind of information or
do you have other resources that are not so time consuming?

1. Asking questions here ;-)

2. exploring pas files from Delphi\Source directory (vcl and rtl\win). I'm using Delphi 5.

3. examining projects from Delphi\Demos directory.

4. msdn, Delphi related sites, etc.
