Thanks for all the advice. The new laptop is here and so far installation of PS and LR have gone smoothly, adobe just asked me to sign out on the other account. Win 11 was pre installed. I will try to download the NIK plugins later. I have decided to transfer my pictures on LR manually, they are all over the place at the moment and it will give me an opportunity to cull many thousands of unwanted images. I am going to dump everything on a 5TB hard drive as a back up before I start. There is nothing that would cause me real problems if it went wrong as I am a hobbyist so do not have to explain to clients how I lost their pictures. Hopefully this new laptop will last for a good few years. I have promised myself that going forward I will cull unwanted images as I go...but I said that last time!
Until a few months ago, I had photos all over the place, lots of discs taken out of past machines, cloud storage, several PCs in the house.
I had made several attempts to sort them, which had just made things worse.
Two programmes I use now, to sort them I used
https://www.mjbpix.com/upgrade-to-photomove-2-0-pro/ it allows you to select a drive or folder, and it will find all the photos on that drive or folder, and move then to a destination, sorted how you choose, I chose camera model and year. It then creates folders for each model of camera, and within those folders, folders for the years in which photos were taken. That works for me, but there are other choices.
Once I had that done, and copied to several locations, I then use SyncFolder (available from the MS store for free) to sync all the directories on the machine I am working on to a 2TB USB drive, I then sync that to a server, and from that to two NAS drives. All my photos are in one "parent" folder, makes it simple to sync it all.
Now everything is sorted in a way that I can find things reasonably quickly.
There are dedicated programmes and systems for professionals, but nothing I could justify the cost of, or that I found easy to work with
