Another good author is Darrell Young in which I have his book on the D7100.
Nikon's website when you are checking to see if there is new firmware for your camera has a section that explains what to do from downloading etc.
I use Photo Director and have used CyberLink products for years.
Thank you in welcoming me.
I use Lexar mainly but have Sandisk, Kingston, Transcend and Sony a collection of 23 ranging from 8GB to 128GB.
