Hide sub folder

I see some mentions about hiding folders in the forum but none quite get to what I want; also most posts are pre infuse.  So my question is how can you hide a subfolder in one of the media folders?  I am using GoodSync to mirror a couple of remote directories (with videos) and the GoodSync program uses a special folder called gsdata to store backup details.  This folder shows up in infuse and I do not want to see it.
