    Hi all.
    Has anyone else noticed this?
    When I use the desktop version of Dropbox, uploads create an incredible amount of data being uploaded - compared to the filesize. For example a file of around 20 MB can create 100 MB of upload traffic!
    When I use Dropbox's webbased uploader, they somehow know how a upload should work and traffic is normal.

    What angers me most: people I collaborate with, using Dropbox, are not even interested in the problem! So I am forced to continue using it with these sheeple.

    Has anyone here also noticed, that the desktop version creates a big "overhead" of data traffic?

    I don't use Dropbox myself, but this is interesting.

    Maybe record a packet log, and look at it under e.g. Wireshark?

    Also, it would be interesting to just look at a firewall log (preferably external firewall) and see where the extra traffic is going.

    I had checked it with Networx and there were three or four Dropbox-destinations.

    Thanks for the tip with another software. But I don't think there is any chance to see, what is being transmitted. If it's a criminal company that spies on users ~ Removed Off Topic Remarks ~, then I assume the traffic will be encrypted.

    I sure would hope the traffic is encrypted, otherwise MITM attacks are possible!

    However, not all traffic in an encrypted connection is necessarily fully encrypted.

    e.g. HTTPS traffic may have destination hostnames in plaintext. Even for other encrypted protocols, parts of the protocol may be plaintext.
