My idea to move images from ext drive into internal drive and primarily goal wast to rename and apply presets and get the images in the new folder.
It is completely unnecessary to move photos in order to do this. You can leave them where they are, if that works for you.
If I drag and drop the whole folders how can I rename them and apply presets?
Rename via F2 in the Library Module; apply presets in the Develop Module.
That explains what to do for photos that have already been imported into Lightroom.
If you are importing new photos, you can do all of this using the Import Dialog box.
