Upgraded from Win 7 to Win 10 yesterday [free update]. Checked my Docs containing my phot folders. Last one being Plant Pathology. Folder is missing. It's taken me months building this folder.
In the Start area, I recognized one of the missing pics, displayed as a tile. Did something that removed the tile and listed, 'photos' in the margin. Clicking on this, the screen opens up showing my lost pictures but in reverse order. Also a vast number of other pictures that are saved in My Docs, but individual folders.

HELP PLEASE. Can I take whatever steps to restore my folders to My Doc's and at the same time prevent windows from ever again making collections.
Many thanks.
