Google Drive is a fantastic tool for sharing files and folders. When working with shared folder structures, follow these best practices:

• Share folders at the Can view, not Can edit, level (Share at Can edit level only when necessary)
• Pay attention to where files and folders are; if they're already in a folder, don't move them (you'll know an item is already in a folder if there's a folder name to the right of the filename)
  
• Avoid dragging files into My Drive (use Add to My Drive  instead)
