I thought that there would be a post on this already but couldn't find one. When I first got my E-PL1 99% of my photos were of my daughter so they all went in a folder named Brielle and then were broken down in that folder by age in months. Then I started taking more pictures of other things like landscapes and flowers, so I started another folder for that. Then I opened one for other peoples kids. Now I've got dozens of folders and I end up sorting all my photos into them. To complicate things a little more , we are expecting another little one in a couple months. What do you do to keep track of all your photos? Do you sort them by date? Event?
