Add .dropboxignore directory to exclude folders without using selective sync

I’m not sure what could be more convenient and appropriate within this context as right click, don’t sync to Dropbox. It is not selective sync at all, selective sync lets you only download certain folders you specify and the rest are ‘hidden’ in the sense that they only are visible to you on the web/through a browser. That’s not what this command does. It removes that folder and anything in it from your Dropbox period. After you run it, go on line and have a look, that folder will be gone yet on your local computer it will be there, still contained within your Dropbox/…. Folder but it will not be syncing or uploading until you tell it to be running the oppose command.
