Hmmmmm...
It works even without the Attrib command. Though I don't understand why I have to change directory first???

This works:
CD C:\Users\Dan\AppData\Local\Microsoft\Windows Photo Gallery
DEL Pictures.pd4

and this does NOT work:
DEL C:\Users\Dan\AppData\Local\Microsoft\Windows Photo Gallery\Pictures.pd4

Oh, I'm leaving on a mini vacation. So if someone replies I may not read your reply for a while...
