删除文件的问题(10分)

我想删除指定目录下的文件，单此目录下还有子目录且含有文件，
请问如何删除全部文件而保留所有的目录，包括子目录在内，望高手赐教！

api
DeleteFolder

好象用FileSearch函数，做个递归，目录和文件有个属性不一样的。

有源码吗？我可以学习学习/

哈哈，hubdog的
uses Windows, Classes, ShellAPI;

const
FOF_DEFAULT_IDEAL = FOF_MULTIDESTFILES + FOF_RENAMEONCOLLISION + FOF_NOCONFIRMATION + FOF_ALLOWUNDO +
FOF_FILESONLY + FOF_NOCONFIRMMKDIR + FOF_NOERRORUI + FOF_SIMPLEPROGRESS;
FOF_DEFAULT_DELTREE = FOF_NOCONFIRMATION + FOF_ALLOWUNDO + FOF_NOERRORUI;
FOF_DEFAULT_COPY = FOF_NOCONFIRMATION + FOF_ALLOWUNDO + FOF_NOCONFIRMMKDIR + FOF_NOERRORUI + FOF_MULTIDESTFILES;
FOF_DEFAULT_DELFILES = FOF_DEFAULT_DELTREE;

function ShellDeleteFiles( hWnd : THandle ; const DirName : string; Flags : FILEOP_FLAGS; WinTitle : PChar ) : integer;
{---------------------------------------------------------------------------------------------}
{Apaga arquivos/Diretorios atraves do shell do windows}
//Notas: Ver comentario sobre o uso de duplo #0 nos parametros de Origem e destino
var
FileOpShell : TSHFileOpStruct;
Oper : array[0..1024] of char;
begin
if WinTitle <> nil then begin
Flags:=Flags + FOF_SIMPLEPROGRESS;
end;
with FileOpShell do begin
wFunc:=FO_DELETE;
pFrom:=Oper;
pTo:=Oper; //pra garantir a rapadura!
fFlags:=Flags;
lpszProgressTitle:=WinTitle;
Wnd:=hWnd;
hNameMappings:=nil;
fAnyOperationsAborted:=False;
end;
StrPCopy( Oper, DirName );
StrCat(Oper, PChar( ExtractFileName( FindFirstChildFile( DirName )) ) );
Result:=0;
try
while Oper <> EmptyStr do begin
Result:=ShFileOperation( FileOpShell );
if FileOpShell.fAnyOperationsAborted then begin
Result:=ERROR_REQUEST_ABORTED;
break;
end else begin
if Result <> 0 then begin
Break;
end;
end;
StrPCopy(Oper, FindFirstChildFile( DirName ) );
end;
except
Result:=ERROR_EXCEPTION_IN_SERVICE;
end;
end;

多人接受答案了。
