Sharing Files to Multiple Users Google Drive allows users to upload and then share files with other users of Google Drive as shown in Figure 1. The person uploading needs to understand the way that file are shared with multiple users since there are three sharing options. These three sharing options each have their own security compromises and differing levels of concern for the information being shared. Figure 1 – Share button and Share Settings option box in Google Drive. The file sharing options, shown below in Figure 2, include, “Public on the web”, “Anyone with the link”, or “Private”. Figure 2 – Google Drive’s Sharing Settings for file access. Recommended Uses for File Sharing Settings Public on the Web Anyone can find and view file Public on the web sharing setting is used to allow anyone on the internet to find your document and view it, without sign-in required. This option should only be used if the file being shared is not of a personal or private nature and is information that is safe to share with anyone that can find the document through Google. Anyone with a link Anyone with a link can view file Anyone with the link sharing setting is used to allow anyone on the internet who has the URL link to the document (Example: www.google.com/example/yourdocument.doc) to access and view the file. Private Only people with owner's approval can access file The last option, private, is the most secure option of the three that can provide the most control over documents on Google Drive. This option keeps anyone but the original sharer unable to give access to anyone further without the owner’s direct permission. Additional Sharing Settings – User Permissions When sharing a document through the Share Setting, the additional options for access and editing capabilities given are can edit, can comment, and can view as seen below in Figure 3. These options dictate what the users given access can do with the document being shared. Figure 3 – Additional sharing setting in Google Drive for sharing documents. Recommended Uses for Additional Sharing Settings Can Edit Anyone can make changes The can edit means that they can edit the document and those changes will apply to all users who can access the document. This option should be used when wanting to have multiple trusted people editing a document. Can comment Only owner can make changes, buy anyone can view and comment The can comment option allows them to comment on the document but not make direct changes; these comments are seen by all users who can access the document. This option is good when wanting to gather comments on a shared document but not wanting others to make direct changes on a document. Can view Only owner can make changes, but anyone can view The can view option only allows shared users the ability to view the document and can make no changes or comments. This option is preferred when not seeking comments or edits and just wishing to share a document so others can view it. Documents like calendars, notifications, or things that do not change much.
