### 3.4 Leaving MH-E

You may now wish to exit `emacs` entirely. Use `C-x C-c` to exit `emacs`. If you exited without running `x` in the ‘`+inbox`’ buffer, Emacs will offer to save it for you. Type `y` or `SPC` to save ‘`+inbox`’ changes, which means to perform any refiles and deletes that you did there.

If you don’t want to leave Emacs, you can type `q` to bury (hide) the MH-E folder or delete it entirely with `C-x k`. You can then later recall it with `C-x b` or `M-x mh-rmail`.

On the other hand, if you no longer want to use MH and MH-E, you can take your mail with you. You can copy all of your mail into a single file, mbox-style, by using the MH command `packf`. For example, to create a file called `msgbox` with the messages in your ‘`+inbox`’ folder, use ‘`packf +inbox`’. The `packf` command will append the messages to the file if it already exists, so you can use ‘`folders -recurse -fast`’ in a script to copy all of your messages into a single file, or using the ‘`-file`’ argument, a file for each folder.
