I have exactly 23008 photos alone in my 'photos' folder(where I import), I just checked lol. This is not even comparable to what I HAD before formatting and backing up clients sessions on DVDs! I'm happy EOS utility takes care of the sorting mostly for my RAW files, otherwise I'd be swamped!

I have a folder for exporting after minor editing(main after RAW), then subs for Renderosity ,500px/ DeviantArt,ModelMayhem and Facebook for my personal photos. Then I have sub folders in another folder for clients per name/date and their various sizes for websites, e-mail and Hi-res.

I need a new harddrive or two ;/
