    Changing attachment size in Windows Mail

    I'm trying to email a file to someone with a 5MB attachment limit. Vista
    reports the file size as 5.4MB. When I attach it to an email, Windows Mail
    reports the filesize as 4.56MB. When I hit "Send", the Windows Mail Outbox
    reports a filesize of 6.2MB - despite the fact that the entire email consists
    only of the attachment and the words "Here you go."

    What's going on and how big is my file?

    PS. I sent it via FTP in the end. I'm not looking for a solution, I just
    want to know why my file gets first smaller, then bigger.

    Emailing adds about a third to the size of the file.

    Try zipping large files, right click>send to>zip, or break them apart using
    your account settings:
    tools>accounts>properties>advanced, set the size to suit.
    The recipient would the use Combine and Decode with all parts selected, from
    the message menu.
    HTH?

    The process that converts 8-bit binary to the 7-bit protocol allowed
    in mail increases the sent attachment size by some 33%. As to why
    Vista initially gives a bigger size, it includes the total disk space
    taken up, which is somewhat more than the actual data in the file.

    Thanks mac - I hadn't found the break apart option before. You learn
    something new every day.

    Thanks Gary - that explains it (although I defy anyone to explain why email
    uses a 7-bit protocol - that's just silly)

    That 7-bit limitation is grounded in the history of email.
    It was originally designed for the transmission of ASCII text only.

    How ironic that a system designed to save a few hundred bytes per message is
    now swelling email bandwidth usage hugely.
