There are three different symbols that may appear next to files after performing a verification. 

A Green Check indicates that both items match completely. A Yellow Caution indicates a partial match. Finally, a Red X indicates the items do not match or an item is not present.

In the event that an item is missing from one of the compared folders, the item name will appear in gray text where it would be in the folder it is missing from.

Hover your mouse over any of the icons to learn more information.
