For folders on your computer, when you connect with EOS Utility you can select which images to download and to where:
1) Connect camera, and power up. EOS Utility should start.
2) "Download images to computer"
3) "Select and download"
4) Select individual ones from one city, then click "Download..." in the lower left
5) Select "Destination folder" in the dialog box
Now you can browse to the desired destination folder and an optional subfolder with a naming scheme. You will want to uncheck the subfolder part and just save in the selected destination. When the dialog box looks right, click OK and the images will download to the city folder you chose and DPP will launch. At this point I always flip back to EOS Utility and, while the chosen images are still selected, delete them from the card.
