But date taken is not capture used for raw files - e.g Nikon .NEF files. Nikon's Date shot is captured into date taken for JPEG files and accessible via file property details. No such luxury for raw files.
I would appreciate it is someone could verify my conclusions below.
After many painful experiences when file tweaking timestamp data (due to operator error in camera) I have found it seems upon first import Nikon's Date Shot is used to populate date created and date modified value (as seen in NXStudio opening an external camera card formatted as ex-fat (what Nikon use)- which is fair given the above. When imported these into files into File Explorer the files date value is set to the imported date modified value (at this point the same as date taken/date shot value). Any future manipulation of the files like refining their name to help File Explorer to sort them faster (instead of what seems to occur opening each file to get date info and then sort) will update the file's date modified but note the date is still as it was when imported set at date created. Again I guess this is as it is designed and fair. If you however copy or move such a file however the date field inherits the date modified date and updates based on current date and/or the new date created date. etc etc
What is desperately needed to massively simply large volume based file manipulations is a field with date shot i.e. the already used for JPEG but not for RAW date taken field. As it doesn't exist there can be no retrospective issues surely. I'd like a solution please that doesn't require me to use third party tools or hack how explorer works
