Storage Card Path Identification

I responded to a thread on Google Groups about the "correct" way to identify the Storage Card path on Windows Mobile devices back in February 2007 (link). According to the Windows Mobile Team Blog, you should use FindFirstFlashCard (link). I've used it successfully on a variety of HTC WM5 SmartPhone devices, however, this issue has recently cropped up as a (potential) issue for one of our MyExperience tool users. The crux of the problem is that you cannot assume \Storage Card\ will be the default path for the storage or flash card on your Windows Mobile device, which is why FindFirstFlashCard is necessary. For example, on the Fujitsu LOOX PocketPC, the storage card path is \SD-MMCard\. The problem seems to be that either some device manufactuers don't properly support the FindFirstFlashCard method or that certain libraries on the device do not use FindFirstFlashCard and improperly assume the storage card is at \Storage Card\. More investigation is needed.

The code I use in MyExperience (actually, the Roam library which MyExperience relies on):

public static String GetFirstFlashCardPath()
{
Win32FindData win32FindData;
IntPtr intPtr = FindFirstFlashCard(out win32FindData);
String path = win32FindData.cFileName;
FindClose(intPtr);

if (String.IsNullOrEmpty(path))
{
throw new ResourceNotFoundException("
Could not find a flash card on this device");
}

return path;
}

The full code is available here.
