Folder Marker is a tool that allows you with a simple interface and integration with Windows Explorer, customize the icons of your folders.
But above all, Folder Marker Pro allows you to use an option "Propagate custom icons" to apply changes icon hard.
Specifically, when you change the icon of a folder on a removable medium such as an external hard drive, this change applies only to local and disappears when the disc is played on another computer. With Folder Marker Pro, these changes follow you everywhere, regardless of the pc on which you read your files and without Folder Marker Pro does not need to be installed.
