Sorting
Sort the grid twelve ways, ascending or descending. Sorting only changes the order you see; it never moves or renames a file. Each folder keeps its own sort.
Set it
Open the Sort & organize button in the top bar and pick a field under Sort by, with a toggle for ascending or descending. You can also right-click a folder in the sidebar to sort just that one, or set a default for everything in Settings, under General.
