microSD card questions

[jfolliard]

The documentation is very thin on the sd card. How do you tell what files are on the card other than plugging it into the computer?

I don't understand how email handles attachments. When I d/l an attachment to an email, does it go directly to the sdcard? Often I just need to look at the attachment once then have no reason to save it - does it stay on the card until I delete it? Seems strange way to handle attachments but maybe I'm totally wrong.

Do images from the camera go to the card?

Can anyone point me to a thread which explains the usage of the card and various tips and tricks?

Thanks from this hero-newb
