Thanks David, helpful info, pointing out the difference between 'image date' and 'today's date' as they are nearly always one and same for me, that's little difference, but still, good to know.
I guess I do use C1 slightly as a 'browser' - I review that days images with it, rate them 1* to 5***** (which I had more of those!) then delete any that didn't even get 1*. With IQ100, in LLQ or LLQ16bit, and a lot of shooting, I've had to bite the bullet and delete files that don't even earn a single star. Yes I have a 28Tb Raid array here, but still. I shoot about 32Gb+ a day, it's necessary to cull. But that's it, I don't do anymore, metadata, keywords, etc don't interest me. I'm not a stock agency, or running a commercial celebrity photo business. Everything is my personal work, and I simply want the best quality an ordinary mortal can obtain, so use P1 backs and C1 to raw convert. From there on everything is in Photoshop. Lightroom does not convert IQ files that well (no surprise) so I don't bother with that at all.
Still don't get why the logical path (when creating a single folder) is not logical to you/C1, but we're talking past each other at this point, so I'll let it drop.
(Could you at least put a 'Delete all Session Albums' command in there, so I don't have to manually go through and spend 10 minutes deleting 80+ one by one, every few months?!)
