Thanks everyone.
I decided many years ago not to use dates in my folder names as I didn't want names to be too long and for me searchable information was much more useful (who what where etc) and I could always use (mac) finder to sort by date created if I needed that reference ..... which I quite often do especially for recent work.
I will look into options for changing modification time to created time on mac .... that could be a useful work around if it was easy, quick and safe to do.
Just out of interest Kirk is it actually impossible to use Date created as a sort option for folders .... could it ever be a feature?
If it is impossible I guess that would also explain why Lightroom also doesn't offer that kind of functionality .... LR doesnt allow any kind of sort option in the folders panel
..... I know LR isn't designed to be used in that way but I know I'm not alone in wishing it did.
cheers
