In this basic Android file manager app, each file has an overflow menu. The overflow menu list contains too many items (actions) AND the items are disorganized and randomly sorted. Because of these 3 things, it creates heavy cognitive load for the user.
Heavy cognitive load required for making decisions usually results in the user (a) choosing a wrong or unintended item, or (b) avoiding using the app. That is why heavy cognitive load is bad for UX.
Solution:
Items should be grouped in an organized way, OR rarely-used items should be moved to a secondary menu (ie, “Other”).
