While I owned only one D100 life was simple. There was a folder 101ND100 on all memory cards I used. Now that I bought a second D100 I can't get the folder thing sorted out. My cards now have 101ND100 and 103ND100 folders. If I delete the 103 folder (on my computer) it comes right back when I shoot the first picture. I select folder 101 through the camera menu, take one shot, it's in 103 which the camera just formed. How can I get rid of this stupid behavior? Ideally I want two folders on each card and have each body be set to use its own folder. That way I can track which body made which shots. I have looked in the manual and can't find anything but the most basic info on folders. Naturally it doesn't cover this issue.
