Sorry for this seemingly simple question, I did a search on 'Date taken' (and looked in the 'command line' section of the helpfile).
But the search query yielded to many search results so I might have missed the topic regarding this.

My question:
Is it possible through command line to rename an image to it's 'Date taken' field?
An example with the TIME and without TIME (if possible).
Is it also possible to process a whole folder?
