If you’re using Gmail often there’s a nifty feature you can use to get more information when you’re adding attachments to messages.
To use these, head to the settings menu through the “gears” icon in the top-right hand corner of the screen.
At the bottom of the screen, you’ll see an option to use “advanced attachment features”. Turning these on gives you progress bars, and the ability to attach different files at once. However, you’ll need to use Flash.
