I use an SD card for podcasts and would love to figure out a way to manage the files more easily. I currently use ipodder and I end up with a set of files/directories on my computer, then I manually copy them over to the SD card in a reader. I then copy over the files into a "synced" directory, and when ipodder runs again, it brings over any new files. I'd love to have a program that kept track of which files had already been put on the SD card, and when I deleted them from the Treo, not re-sync them. Then only copy over files that were new. Anyone know of such a program?
