My DNG file is 22 mb but in lightroom, the pixel size is only 3360x2240 which translates to 3.8mb.  I have zero cropping.  What's going on?  How can I go from 22mb to 3.8?

If part of the problem is a change in pixel dimensions, where no cropping has occurred, is there the possibility that you are dealing with Smart Previews instead of the original images or that some mobile upload/download is involved?

>> My DNG file is 22 mb but in lightroom, the pixel size is only 3360x2240...

This does not compute. 3360x2240 is only 7.5 MP. An uncompressed 14 bit Raw/DNG would be 12.5 MB, but DNGs are compressed. I have old, archived 8 MP DNG files that are 6 MB and 21 MP files that make for 20-24 MB DNGs, while 24 MPs are about 26-30 MB. Maybe you have the original Raws embedded in the DNGs which would around double their sizes.
