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','');
