\\ in image file path

Using Xp pro. English but localised keyboard.
Visual studio Express C++
Win32

I found a Ms gdi+ sample "Loading and Displaying Bitmaps."

In it was following code.
Image image(L"Grapes.jpg");
graphics.DrawImage(&image, 60, 10);

When I tried it here \\ was needed in path. Like this:

Image image(L"F:\jpegit\\2007.JPG");
graphics.DrawImage(&image, 60, 10);

Or even

Image image(L"c:\\20.JPG");
// Image image(L"F:\jpegit\\2007.JPG");
graphics.DrawImage(&image, 60, 10);

Rest of the program is a line drawing sample.

I know that old "feature" of \\ in top folder, but what is this. Is it
in my machine or what? Any info?
