This is not likely a situation many will encounter, but I thought it interesting enough to note.
I've been going through a large mass of photographs from a recent trip, with the aim of making a CD for friends. I don't usually do a great deal of editing for this, and use Faststone Image Viewer or Irfanview for the conversion. When some exposure compensation, white balance, etc. is needed, I take the Raw file to one of the basic Nikon editors. In the past, I've used View NX-2. Faststone allows editing in an external editor, and return to Faststone, whereupon one can save the JPG from there. I like this option, as Faststone's cropping, among other things, is very efficient. However, since my wife got a D7200 whose files are no longer editable in View NX-2, I've had to do this in Capture NX-D instead, and although that program works fine, the edited result is not read by the Windows NEF codec. I can edit a file in Capture NX-D, but when I return to Faststone, the version loaded is the unedited one. Apparently the editing to the "sidecar" file, while quicker by far, is also not picked up by other Windows programs.
As I say, this is not likely a problem for most, but I thought it an interesting change in the way Raw files are processed by the Nikon programs, and read by Windows.
