Even Apple official recording APP cannot attach multiple recording files on your e-mail at once. That is why I tried this. From version 2.17, the function is available.
Not only for the recordings, but also your picture or video can be attached on your e-mail at once. To do so, go to the answer page and tap the title of your question with underline. For more information, visit my CQ-BBS.
The text information and reference URL can also be attached as well. Please share your information with your friends!
