Well, it's kinda difficult to give a general answer. Besides, your question lacks detail.
Despite being only visible in the shell name space, your device (camera or mobile phone) will typically have its own display name. So in theory you should be able to abuse
SHGetDesktopFolder in order to get an instance of
IShellFolder and calling its EnumObjects method to retrieve a
IEnumIDList instance. Using that you should be able to forge a PIDL that corresponds to the shell namespace object representing your device and use that in
SHFileOperation or the newer
IFileOperation.
Do you have a minimum compatibility requirement? If XP and newer is okay, then you may want to look at
WPD Application Programming Interface, which may or may not be easier to wield in your scenario.
