Folder Marker

Folder Marker is utility that can mark folders by priority, by degree of work complete, and by the type of information contained in the folder, using colour coded icons. This can be useful in organising family research records.

See and for details, and note that there are Pro, Home and Free versions.

Tip: If you colour code a folder that appears in the Windows File Explorer Quick start list or a shortcut, then that entry may not automatically inherit the colour. The workaround is to move or refresh such shortcuts, or delete and re-insert them.
