How do I download pictures and videos from my sd card to my computer.....I do have a card reader.
Most of us take the SD card from the AC and put it in our computers to transfer the media files. That is one easy option for you to consider and one I know you've had success doing before.
First real flight
Remove the SD card from your AC.
Put the SD card in your card reader.
Connect your card reader to your computer if it's not already connected.
On your computer, browse to the drive location of the media files.
Move the media files to a location of your choosing.
Note that there are several other ways to do what I described above.
Also if I get this accomplished how do I get the pictures and videos to a flash drive.That"s is what I am trying to get done.
Once you've moved the media files to your computer, simply plug in a flash drive and either cut/paste, copy/paste, drag/drop (etc) the files to the flash drive. There are also several other ways to do this step.
You could also move them directly from the SD card (in the card reader attached to your computer) directly to a flash drive also attached to your computer. That's if you aren't planning to store the originals on your computer at all. I think that most of us would first move them to our computers, review them, delete throwaways, etc before sharing them.
What
@Tagmaster described
above is also an option to consider. It is a more current and more convenient option for some. A lot depends on your comfort level and that of your audience.
