An emblem displays unusual or non-default status information about an icon or image. For example, an emblem could indicate that a folder is shared, that a disk is unmounted, or that an app has unread notifications.
Emblems are used to badge icons, images, or other visually discrete elements in a file manager, system tray, task manager, dock, image view, etc. Emblems should not be applied to textual content.
Use emblems to display that an icon or image has some unusual status associated with it, or that there are unread notifications. Don’t use emblems to display an element’s normal, common, or typical status. For example, an emblem could indicate that a folder is read-only or is a symlink, or that a disk is unmounted or encrypted. An emblem should not be used to indicate that a folder is read-write or that a disk is mounted.
Emblems that indicate status should be placed in the bottom-right corner. If additional status emblems are needed, they should be placed in other corners in a clockwise order.
Emblems that indicate unread notifications should be located in the top-right corner.
Use the minimum number of emblems and don’t overwhelm the icon itself. Three is usually too many.
