How it works?
When you are browsing through dozens of visually similar folders, you are not using your vision to its full extent and thus your activity is less effective than it could be. But if some of these folders have a different color, they will catch the eye faster than you read their name. This way you can easily differentiate between folders and browse much faster, because you are using your vision much more efficiently.
Folder Highlight is very easy to use no matter how much do you know about your PC. To change color of a folder, right-click the required folder with your mouse, select Folder Highlight in the context menu and then choose a suitable appearance for the folder.
