I'd listen to what Phoenix said for sure.
What is an .eml file?
"What is an .eml file?
An .eml file is a special file that has the .eml extension. These files contain Outlook Express e-mail, and can be opened and viewed in Outlook Express. You can open an .eml file by simply double-clicking it.
You can convert a piece of e-mail to .eml format, and store it on a floppy disk, Zip disk, CD-R disk or CD-RW disk. Once the .eml file is backed up and stored, you will never lose that piece of e-mail.
In the event you accidentally delete a piece of e-mail from Outlook Express, or if you suffer a hard drive crash, you can restore the original e-mail from the .eml file. This can be done with a procedure known as "drag and drop," which I will explain momentarily.
You can also use .eml files to move a piece of e-mail from one computer to another.
Files with the .eml extension can contain only one piece of e-mail. You cannot put several pieces of e-mail into one .eml file."
but this page says .eml's could be a
virus, so I'd
let the computer experts weigh in before doing anything.
