Finish Importing
Choose a name for your new folder, and enter description of the pictures. This information is all searchable, so it's good to enter lots of detail about the location, event, and people involved.
If you are importing pictures from media card or a camera, you will have the option to Delete pictures from source when import is complete. This will clear all the files off your card or camera so you'll have plenty of room to take more pictures.
Note: If you exclude pictures and then clear your card, all pictures will be deleted, even the excluded ones.
That's all - the final step is to click the Finish Importing button. Your new folder will be saved in your My Pictures directory. Now it's time to play with Picasa's Editing features.
