{-------------------------------------------------------------------------------
过程名: MakeFileList 遍历文件夹及子文件夹
参数: Path,FileExt:string 1.需要遍历的目录 2.要遍历的文件扩展名
返回值: TStringList

USE StrUtils

Eg：ListBox1.Items:= MakeFileList( 'E:极品飞车','.exe') ;
ListBox1.Items:= MakeFileList( 'E:极品飞车','.*') ;
-------------------------------------------------------------------------------}

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;
end;
