Lightroom is a good website for organizing pictures as well as enhancing. You can use file folders and put the same photo in multiple files. I have a lot of file folders: Places, Family, Woodwork, Birds and Animals, Ranch, Fishing, Hunting etc.
I might have a dozen sub sets in each folder....Fishing: Saltwater(offshore & inshore)... Freshwater( Texas, Louisiana, Alaska, Wyoming, Colorado, Brazil etc)... Boats....Rod building etc. I will have a Friends folder from photos I receive.
Hunting is much the same other than I will have locations such as RTK which is ranch in Colorado and then have decades of subsets by year.
To me if you don't have a system it is extremely difficult to ever find what you are looking for.
Back them up. I had a hard drive that failed...my back up drive failed...my online system cut me off when they couldn't get paid due to a compromised credit card. They never contacted me. Some computer gurus worked about two months on my hard drive and they recovered about 90%
I think that is what you were asking.
