I then ran the command “dir file_prefix* /s /b” where file_prefix was the first word in her lost file name, the * (star or asterix, obelisk is another guy) is the wildcard character.

I copied this file from its location to her Sky Drive or whatever its called and B was back on track. I suggest you bookmark, save, store this information for a rainy...

The 10 Commandments of Photography

The 10 Commandments of Photography   Here’s something new. A photography article with no pictures. There is one rule you need for taking great photographs. It was a favourite saying of noted British nature photographer Heather Angel and most of the 10 Commandments come from this simple phrase: "f8 and be there" Read on to see why that’s all you really need to know. You can’t take a picture without a camera. Take one with you everywhere because you never know what you will see or where or when. You can’t take a picture without the camera being ready. Keep it clean, fully charged and with enough memory/film to take the shots you find. You might well have a fairly small and simple one on you at all times. It will be the one you use when you’ve left the SLR in the car because it was too heavy. You can’t take a great picture without knowing how to use the camera.
