the birds wallpapers are in user/share/deepin-system-settings/modules/individualization/backgrounds/deepin
found using the search suggestion; open file manager. go to computer. click the search option. type "png" and lists all png files and location.
hope this helps anyone else as the birds get removed on upgrade so have to save them to another place before update and upgrade and then paste them back if you want to use them.
wallpapers are usually in user/share/backgrounds but only contains one wallpaper.
in personalization there is a selection of wallpapers
where are these stored?
where are the birds wallpapers?
an upgrade replaces the birds and I want to copy them and keep them.
