And when I was done, I would put them in the " outbox" (outbox) – all one word.

当我完成后，我会把它们放在“发件箱” （outbox）中——都是一词。

There's a third folder on most email programs called an " outbox."

多数电子邮件程序中都有第三件夹， 称“发件箱” 。

I take the papers and files from my outbox and put them in my coworker's inbox.

我从发件箱中取出件件，并将它们放入同事的收件箱中。

An " outbox" contains the messages that you are ready to send, but haven't actually sent yet.

“发件箱” 包含您准备发送但尚未实际发送的消息。

So your outbox contains messages ready to send; your sent mail folder contains messages you've already sent in the past.

所以您的发件箱包含准备发送的消息；您的已发送邮件件夹包含您过去已经发送过的邮件。

So, we have an " inbox, " and an " outbox." Well, one of the things you can send via email – that is, through email, is " attachments." An " attachment" (attachment) is another file.

所以，我们有一“收件箱” 一“发件箱” 。嗯，您可以通过电子邮件发送的东西之一 - 即通过电子邮件， 是“附件” 。 “附件” （附件）是另一件。
