How can I better organise and file my photos?
I've just purchased a DSLR camera. As I wait for it to arrive I'm wondering how I'm going to keep my photos organized as they start to add up. Of course I've been taking snapshots of family, etc for years. But I've never really figured out a good organizational system. I will soon start to take more and more photos for artistic purposes that have nothing to do with my previous categories of photographs.
What are some ways that I can organize all these photos so that I know which folder houses a given photo?
Note: Could someone make this a community wiki?
