Folder Marker does not work with Dropbox

Q: I have copied a folder into Dropbox but there is a default colour on another user's PC. The "Make customized folder distributable" option is enabled.

A:

Unfortunately, Dropbox ignores the "Desktop.ini" file, which is responsible for colour changing. Therefore, this folder does not syncing to another computer.
