When you receive attachments—for example, Word documents or photos—Thunderbird keeps them with the e-mail message they came with. To open or view an attachment, or to save it as a separate file, find the e-mail message it came with and right-click on the attachment at the bottom.

Saving attachments

To save attachments for a single e-mail message, you can use any of these methods:

  • Right-click on the attachment name or icon in the "Attachments" pane, at the bottom of the window, and choose "Save As..." (to save only the selected attachment) or "Save All..." (to save all attachments at once). In the dialog box that pops up, you can choose where on your computer you would like to save the attachments.
  • Using the "File" menu: look under "File -> Attachments" for the "Save As..." and "Save All..." options.
  • Using your mouse, select an attachment in the Attachments pane and drag it to your Desktop.
  • Double-click on the attachment in the Attachments pane. See Actions for attachment file types for further details.

Separating attachments from messages

In Thunderbird 1.0x, there is no built-in means to detach or delete an attachment without deleting the entire message itself. This functionality is, however, planned for Thunderbird 1.5. In the meantime, you can try the Thunderbird Attachment Tools extension.

Technical details

Most e-mail programs use MIME to attach files to e-mails. MIME converts the file to a format compatible with Internet transmission (i.e. "encodes" it) and attaches it to text of the message, creating one large e-mail. Then the whole e-mail, including the attachment, is sent together.

Thunderbird stores the whole e-mail together, including the attachment, in MIME format in the mailbox files in your profile folder. It does not un-encode and detach the attachment unless you save it as a separate file (instructions are above), and even then it keeps a copy with the e-mail (again, see above). By contrast, the Eudora e-mail program automatically un-encodes and detaches the attachment when you receive the e-mail; it always stores attachments as separate files.

To see an e-mail attachment after MIME processing, send an e-mail with an attachment, then in your Sent folder highlight the e-mail you sent and click "View -> Message Source".
