Free up space by only deleting older photos past a chosen date Google photos app has a "free up space" option where it will delete all photos that have been already backed up to Google photos from the local device folders. 

The problem with this is that the recent photos I need can be accessed faster so long as they are on the local device. Eg. No internet access needed unlike from Google photos. 

Is there a way to only delete those photos (which have been backed up to Google photos) but are older than a certain date? 

That way, say, photos more than a month old can be deleted ( this freeing up space) but the current photos stay available on the device  for me to use easily. 

Any way to achieve this?
Connect you phone to the computer via USB cable and use your favorite files management tool.
