Unshare a folder

To unshare folder with someone, you need go to "Folder info" 1 , click on "shared with" link 2 and then on X 3 , which appears in the upper right-hand corner of that person’s avatar when you move the cursor over it. If the X doesn’t appear above a person’s name, then it means the parent folder is shared with the person and you need to go up to the parent folder level to unshare the person from there.
