You can share folders and files in your Dropbox account with anyone (even if they don’t have a Dropbox account).
You can control whether people can edit, comment, or only view your files and folders, when you share them, and after you share them. Edits or comments that are made to a file or folder are updated live for everyone who they’ve been shared with.
Note: Users with individual Dropbox accounts need to explicitly add folders that you share with them to their Dropbox account. If you are a member of a Dropbox Business team, any personal folders that you share with other teammates will automatically be added to their Dropbox accounts.
