I've a bunch of year folders from years ago when I only produced what's now seemingly a month's worth of pictures in a year. Now I'm dumping pictures onto a harddrive every 6 months or so. I'm planning on dumping everuthing into one folder and writing a shell script to sort them into 'yyyy/mm/yyyy-mm-dd'. Just need to work out how I'm doing that. I don't use or trust online storage.
