Powershot SX230HS, CHDK ver 1.4.1 Rev 4343
Is there an easy way to download my DNG images to my laptop (Windows 10) ?
I saw mention of a setting to enable this but I dont appear to have it in my build.
I am just hoping there is a simple setting to make this work, anything too complex will probably be above my level of understanding 
The old "DNG visible over USB" option is unfortunately only possible on very old cameras.
However, DNG files may be visible if you use the correct combination of RAW prefix and RAW extension, and do NOT select "'DNG' file extension"
The working combination may depend on the camera. I'd suggest trying CRW_ .CR2. I would avoid IMG_, because the canon firmware gets confused when you have multiple files with the same prefix (E.g. IMG_xxxx.JPG and IMG_xxxx.CR2)
If you do this, your files will have a .CR2 extension when you download them, even though they are not the Canon CR2 format. You may want to rename them to help windows programs recognize them correctly.
Also, even if you have the right combination of prefix/extension, they probably won't be visible unless you reboot the camera between shooting and connecting USB.
Alternatively, you can download any files from the camera using the CHDK PTP Extension
http://chdk.wikia.com/wiki/PTP_Extension but this is more complicated to set up, and disables standard Windows USB access to the camera.
