Adjusting sharing permissions is a crucial way to prevent unauthorized file sharing in Google Drive. This option allows you to specify who can access your files and folders and what actions they can perform. You can set permissions to be view-only, comment-only, or edit, ensuring that only trusted individuals can make changes or share files further.
By carefully managing these permissions, you can significantly reduce the risk of unauthorized access and sharing. For example, if a file is shared with someone as 'view-only', that person cannot share the file with others or edit it, thus maintaining control over how the file is distributed.
Other options, such as reducing the number of users in a folder or increasing the storage limit, do not directly impact the security of file sharing. Using a different document format also does not affect the file's sharing capabilities or permissions in Google Drive. Adjusting sharing permissions is the most effective measure for maintaining security and controlling who interacts with your documents.
