If you use two PCs (say, a desktop and a laptop) to collect e-mail, you might need to copy messages from one to the other. Eudora stores and catalogues the contents of each of its mailboxes in two files: an .mbx text file that contains all the messages in a particular mailbox, and a binary .toc (table of contents) file. To copy the contents of a mailbox from one computer to the other, you must copy both types of files.

Suppose you have a mailbox named Budget that exists on both your desktop and your notebook, and you want to transfer mail from the former to the latter. Copy budget.mbx and budget.toc from the desktop system's c:\eudora folder onto a floppy ù or e-mail them to the other system. Rename them budget2.mbx and budget2.toc, respectively, and copy them to c:\eudora on the target system. Close Eudora, and then reopen it. You should see a Budget2 mailbox listed in its mailbox directory.

Open the Budget2 mailbox. Press <Ctrl>-A or select Edit-Select All. Right-click the selected messages, and pick Transfer from the pop-up box. Then move all the messages into the main Budget mailbox and delete the Budget2 mailbox.

Batch-forward several messages. Forwarding a slew of messages is a pain because you have to open each message before you can address and send it. But here's a painless work-around. Create a new mailbox (select Mail-New). Then move each of the messages you want to forward into that mailbox by right-clicking the message and selecting Transfer. When you're finished, close Eudora. Next, in your text editor, open the file bearing the name of that mailbox followed by an .mbx extension, as in budget.mbx, and you'll see all your messages, one above the other. Copy and paste this file into an e-mail message, and mail it to your recipient.
