求教如何得到某一路径下的所有文件名？

[lsk2000]

可以的话，我想根据扩展名进行筛选，请大家帮忙看看。

用一个循环，我这有个把文件夹里的文件全部加到树上的例子，你自己改改吧，
var
SearchRec : TSearchRec;
ItemTemp : TTreeNode;
begin
with ATreeView.Items do
try
BeginUpdate;
if ADirectory[Length(ADirectory)] <> '\' then
ADirectory := ADirectory +'\';
if FindFirst(ADirectory + '*.*', 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
ARoot := AddChild(ARoot, SearchRec.Name);
ItemTemp := ARoot.Parent;
DirToTreeView(ATreeView, ADirectory + SearchRec.Name, ARoot, AIncludeFiles);
ARoot := ItemTemp;
end
else if AIncludeFiles then
if SearchRec.Name[1] <> '.' then
AddChild(ARoot, SearchRec.Name);
until FindNext(SearchRec) <> 0;
FindClose(SearchRec);
end;
finally
EndUpdate;
end;
end;

procedure TForm1.Searchit(Dir: string);
var

用WINDOWS API库函数来做
