My photo storage is A Mess. At one time I had a fairly reasonable filing system. Then I got a new Nikon that came with all sorts of software and I started downloading using Nikon Transfer. Then I decided to learn to use Photoshop. All of these programs store the photos differently and when I start to look for something, reverting to my own filing system, I find things all mixed up. Photos have been added to folders that they don't belong in, huge folders have been created by date, sitting next to folders with one or two photos in them, and I can't find anything.
I got a lovely back-up drive for Christmas and have copied my whole 'Pictures' file onto it, in its confused and unwieldy whole. Next, I am going to take the first file apart, throw out (shudder, sob) a lot of losers, and rationalize the wretched thing. If I don't get this done, may the next bird I photograph shit in my eye!
While plotting out what I am going to do, I actually found three photos that I wanted to use for the 365 project some time ago -- before I lost them.
