function MakeFileList(Path,FileExt:string):TStringList ;
var
sch:TSearchrec;
begin
Result:=TStringlist.Create;

if rightStr(trim(Path), 1) <> '\' then
    Path := trim(Path) + '\'
else
    Path := trim(Path);

if not DirectoryExists(Path) then
begin
    Result.Clear;
    exit;
end;

if FindFirst(Path + '*', faAnyfile, sch) = 0 then
begin
    repeat
       Application.ProcessMessages;
       if ((sch.Name = '.') or (sch.Name = '..')) then Continue;
       if DirectoryExists(Path+sch.Name) then
       begin
         Result.AddStrings(MakeFileList(Path+sch.Name,FileExt));
       end
       else
       begin
         if (UpperCase(extractfileext(Path+sch.Name)) = UpperCase(FileExt)) or (FileExt='.*') then
         Result.Add(Path+sch.Name);
       end;
    until FindNext(sch) <> 0;
    SysUtils.FindClose(sch);
end;
