### Viewing Your Photos

You can save files from your camera to your computer. To save, choose File Save Selected to save the selected file, or File Save All to save all the photos in the selected folder.

You can use the checkboxes to decide what is saved. By default, only the photo is saved. You can specify additional data to save by checking the appropriate checkbox.

If you want to use your own filenames, rather than those used by the camera, you need to toggle the Use filename(s) provided by the camera off. This allows you to enter your own filename prefix. For example, if you enter 'photo' as the prefix, the photos will be saved as 'photo0001.jpg', 'photo0002.jpg' and so on. If you want to start the numbering scheme higher, change the Start numbering with number to a different value.

If there are files already in the target directory with the same prefix, this number will be automatically set as the next available number.

If you save all the photos, you can change some additional options in the file selection window:
