I use Canon EOS software to extract photos from my camera. They go to my Pictures folder. I have the EOS software set to name folders as YYYY-MM-DD
I specifically set the separator to be a hyphen, not an underline as I do not want YYYY_MM_DD
Folder names come out in the precise format I do NOT want.
any ideas why this is being overridden? Windows naming screwing things up? Picasa, of course, simply reflects what occurs previously and in any event I don't know of anything there that would amend this for me.
