I hoard my photos ( not advisable )
starting this year, I transfer from SD to multiple folders, designated by " location, date, lens + focal length " used plus other smaller folders: " lens " determinative, and then " subject matter determinative " all stored in multiple external hard drives and some upload to major back up and then I format sd card in camera
for example , " Topeka Zoo 50mm 1.4, 500mm mirror " plus 2 smaller files " SMC Pentax-A 50mm 1.4 " - " Topeka zoo x/xx/2019 " and "Tamron Apdaptall-2 SP 500mm f/8 Mirror (55BB) - " Topeka zoo x/xx/2019 " and then various " subject matter " divisions " Topeka zoo x/xx/2019 bears "
I primarily only do pp on the main folder - " location, date, lens focal length "
and finally after complete pp, I keep those files in date order to the forum and/or flickr.com
I found that I am initially very critical of my photos and then after coming back to them and doing some basic pp, I find more to my liking
so I end up with multiple files, smaller than the primary one.
