why does a workwook increase in size when emailing as attachment
 

When emailing an excel workbook as an attachment, the size doubles and the
mail is returned. What causes the increase in the file size?

When you email a binary attachment, your email program will encode it to
straight ASCII. And the recipient's email program will decode it back to it's
original form.

But I think it was about a 30% increase in space for the attachments I've seen.

You may have seen it in some of your emails when the program gets confused.

begin 666 myfile.xls
M1&EM(&9S;RP@9FEL95-O=7)C92P@9FEL941E<W0-"D1I;2!F:6QE4V]U<F-E

M:F5C="(I#0I3970@=W-H(#T@0W)E871E3V)J96-T*")74V-R:7!T+E-H96QL

And it goes on and on....
