Permissions are rules associated with objects on a computer or network, such as files and folders. Permissions determine whether you can access an object and what you can do with it. For example, you might have access to a document on a shared folder on a network. And even though you can read the document, you might not have permissions to make changes to it. System administrators and people with administrator accounts on computers can assign permissions to individual users or groups.

The following table lists the permission levels that are typically available for files and folders.
