Hàm GetFileList mà bạn có thể sao chép vào Project của MapBasic (lưu ý: cần sao chép các phần: delarations, type, defines…) Function GetFileList(ByVal strFilePath as String,
ByVal strFileFilter as String,
strFileList() as String
) as Logical
Tất cả những gì bạn phải làm là gọi hàm và cung cấp một thư mục bắt đầu strFilePath (Lưu ý: đảm bảo bạn có dấu gạch chéo), bộ lọc strFileFilter (ví dụ: "* .tab", "*. *") Và một mảng kiểu chuỗi lưu trữ các danh sách của thư mục tập tin.
Bạn có thể tải mã nguồn về từ đây: DirectoryScan.mb
