Hello jerry2648,
This is Kevin from Palm. The Palm Knowledge Library article
"Clear up memory on your device" should be of help. If you have lots of photos/videos stored on the device, you can move them to the storage card by going into the camera application, then tap the icon to show your pics as a list. Then you can tap up top for the Menu and under Media, Copy to Card will be one of the options. If you have sorted your pics into albums, you'll have an option to copy an entire album to the card under Albums in the menu. This is better covered in the Pictures and Videos section of your User Guide.
If you have other questions, post them to the Treo 650 forum, as there will be many more folks over there who can lend assistance.
Hope that helps.
Sincerely
Kevin
