- 13 - Working with Images: Copying Images to Disk
Copying Images to Disk
Before copying images to disk, locate or create the destination
folder. To copy images to disk, select the images you wish to
copy by clicking their icons (you can select multiple images by
holding down the shift key while clicking each image in turn),
then drag any of the selected icons over the destination folder
and release the mouse button.
Note: Because the camera functions as a read-only drive, images
can only be copied, not moved, even if the option key is not held
down. If you would like to place an image on the desktop, hold
down the option key while dragging the image to the desktop.
Tip
All images taken with the camera are assigned file names of the form
“DSC_nnnn.xyz,” where “nnnn” is a four-digit file number and “xyz” is a
three-letter extension (JPG, TIF, or NEF). Similarly, all image files saved in
folders in the camera’s memory are assigned file names of the same type.
To prevent images already copied to disk from being overwritten, change
the filename after copying an image, or create a new folder for each folder
on the camera.
