上面一个只获取当前目录下所有文件,如果要获取该目录下的子目录的文件,看下面   
   procedure    SearchFile(path:string);   
   var   
       SearchRec:TSearchRec;   
       found:integer;   
   begin   
       found:=FindFirst(path+'*.*',faAanyFile,SearchRec);   
       while    found=0    do   
         begin   
           if    (SearchRec.Name<>'.')    and    (SearchRec.name<>'..)    and   
                 (SearchRec.Name=faDirectory)    then   
               SearchFile(SearchRec.Name+'\')   
           else   
               LisBox1.Add(SearchRec.Name);   
           found:=FindNext(SearchREc);   
       end;   
       FindClose(SearchRec);   
   end;
