Imported iPhone 6 pictures to windows 7 laptop but didn't take the delete option.

Moved the pictures to a different location on the laptop but am unable to download the pictures a second time.

Also changed the import settings to download to a different location but doesn't appear to make a difference.

Get the message "no new pictures or videos were found on this device".
When I first connect the iPhone I get the message "looking in internal storage DCIM\100APPLE" - it must be this that's the problem , is there a setting to change what it looks for?

Grateful for any help.

Thanks
