  ```lua theme={null}
  local files = openfilesdialog({
      title = "Choose source files",
      defaultPath = ".",
      extensionFilter = { "lua", "luau", "txt" },
  })

  if files then
      for _, file in ipairs(files) do
          print(file:GetName())
          print(file:IsFile())
      end
  else
      print("No files selected")
  end
  ```
