A Folder Compare Tool makes it extremely easy to compare local files and folders on your Mac. It displays compared directories side by side as expandable trees, and the size and date are indicated for each item. Differences between the directories are indicated with color and easy to identify icons.

To copy or delete files or folders, click on an individual item to choose the appropriate action. A red or blue arrow represents the action. Then click "Execute" to synchronize the two folders.
