What is the easiest way to create an e-mail attachment?

First: Create the file you wish to mail. Most programs now allow you to send straight to e-mail as you would a print job but this can be difficult to set up and I don't know the procedure for each program. After you have completed your file, save it to a location you will remember (ex. C:\My Documents).

Second: In either Microsoft Outlook or Outlook Express (procedures are similar for Mozilla's Thunderbird). Compose a new message, giving it a subject and telling it to whom it will be mailed. You can then add text like a normal letter.

Last: Click down in the text area, the paperclip on your toolbar should now be accessible. Click on the paperclip and locate the file(s) you wish to send. Press ok and the file(s) will be added to your e-mail. Send it and you are done. Easy right! NOTE: In most web-based e-mail programs, an "add attachments" button is used rather then a paperclip.

Note: On a system like many businesses and schools have, the e-mail computer is typically in the same building as all of the users. In this situation, the file size really doesn't matter when sending to a co-worker.
However, if you are sending an e-mail attachment to a friend, please be cautious of the file size! You don't want to send anything over 1.5M (1500K) as it will take them forever to receive. Most Internet Service Providers (ISP) will not allow e-mail larger then 2M (2000K) to pass through their system. PLEASE take this into consideration when sending e-mail attachments.
A typical one page text only e-mail is about 1K in size. A floppy disk has a 1.4M capacity.
