Not sure where to put this, but I am thinking about making a small image transfer program for digital cameras in VB.NET, but I have a question about the filesystems on these devices. For USB cameras (cameras that can transfer through USB cables), when you plug them in, the drive is listed as a removable disk drive. You can navigate this drive just like any other drive on your system, and am trying to figure out a way to know that any particular drive would happen to be a camera's drive.

I noticed that on the camera I tested, there is a root "DCIM" folder, which then contains a subfolder of the camera name, which contains the actual pictures stored on the camera's memory card. Is this "DCIM" folder always going to appear? Regardless of the manufacturer of the camera, as long as it is recognized as a USB storage device/removable disk? I know that for many cameras this is the case, but are there others which have some other root folder other than "DCIM"? If not, then its just a simple matter of enumerating the drives looking for that root folder, then just drilling down to the pictures. Any comments would be appreciated.
