PRocedure GetDirectories(list: TlistView; Directory: string; Item: Tlistitem; IncludeFiles: boolean);
var
SearchRec: TSearchRec;
begin
  list.Items.BeginUpdate;//准备更新
  list.Items.Clear;  //清空list内容
  if Directory[length(Directory)] <> '\' then //判断路径 
     Directory := Directory + '\'; //设置路径
  if FindFirst(Directory + '*.*',faDirectory,SearchRec) = 0 then    begin
       repeat  
       if (SearchRec.Attr and faDirectory = faDirectory) and (SearchRec.Name[1] <> '.') then 
         begin
             if (SearchRec.Attr and faDirectory > 0) then                begin Item := list.Items.Add;  //增加item
                     item.Caption:=SearchRec.Name; 
                     item.ImageIndex:=6;
                end;
             GetDirectories(list,Directory + SearchRec.Name,Item,IncludeFiles);
         end
                else
        if IncludeFiles then
               if SearchRec.Name[1] <> '.' then
                   begin
                      item:=list.Items.Add;
                      item.Caption:=SearchRec.Name;
                      item.ImageIndex:=6;
                   end;
           until FindNext(SearchRec) <> 0;
//FindClose(SearchRec);
        end;
    list.Items.EndUpdate;
end;

定义Directory:

procedure makedir(modulname,pathname,dirname,filepath:string);//创建目录(共4级,朋友如果觉得用得上的话,可以自己加参数)
begin
try
   if not directoryexists(frootpath+modulname) then
    createdir(FRootPath+modulname);
   if not DirectoryExists(FRootPath+modulname+'\'+pathname) then
   createdir(FRootPath+modulname+'\'+pathname);
   if not directoryexists(FRootPath+modulname+'\'+pathname+'\'+dirname) then
   createdir(FRootPath+modulname+'\'+pathname+'\'+dirname);
   if filepath<>'' then
   if not directoryexists(FRootPath+modulname+'\'+pathname+'\'+dirname+'\'+filepath) then
   createdir(FRootPath+modulname+'\'+pathname+'\'+dirname+'\'+filepath)
   except
   On E:Exception do begin
   abort;
   end;
   end;
   banjin.N21.Enabled:=true;
  liucheng.MenuItem1.Enabled:=true;
  yanzheng.N21.Enabled:=true;
   banjin.SpeedButton1.Enabled:=true;
   liucheng.SpeedButton1.Enabled:=true;
   yanzheng.SpeedButton1.Enabled:=true;
   banjin.toolbutton1.Enabled:=true;
   liucheng.toolbutton1.Enabled:=true;
   yanzheng.toolbutton1.Enabled:=true;
   if filepath='' then
   filespath:=FRootPath+modulname+'\'+pathname+'\'+dirname+'\'+filepath else
   filespath:=FRootPath+modulname+'\'+pathname+'\'+dirname+'\'+filepath+'\';
   banjin.StatusBar1.Panels[0].Text:='你目前所在的位置:'+filespath;
   liucheng.StatusBar1.Panels[0].Text:='你目前所在的位置:'+filespath;
   yanzheng.StatusBar1.Panels[0].Text:='你目前所在的位置:'+filespath;
end;
如果是二级或一级目录的话,只要加上if filepath<>'' then
类似的判断就可以了,例如:makedir('设计规范','电子件','电路设计规范','');

注:在这里写的两个过程没有实现读取windows的图标,如果想实现这一功能的话要自己动手写了 ^_^
