NTFS Permissions (MCP Series)

NTFS Permissions are different from share permissions. NTFS permissions provide more control over permissions, and override share permissions.

NTFS Permissions can be broken down into two categories:
  • NTFS File Permissions
  • NTFS Folder Permissions
NTFS File Permissions

NTFS File Permissions allow a user to set permissions for a file. Permissions allowed are:
  • Full Control
  • Modify
  • Read
  • Read & Execute
  • Write
NTFS File Permissions are cumulative with the exception of deny permissions. If you assign Read permissions to a user and Write permissions to a group that user is a member of, they will have both Read and Write permissions. If you were to deny permissions to Read a file, under no circumstances (even if they are assigned Read permissions elsewhere) would they be able to Read that file.

NTFS Folder Permissions

NTFS Folder Permissions are used to assign permissions to a folder and all files and folders within that folder. Like File Permissions, Folder Permissions can be assigned to a user or group. Permissions available to assign to a NTFS Folder are:
  • Full Control
  • Modify
  • Read
  • Read & Execute
  • Write
  • List Folder Contents
Copying and Moving Files and Folders

When you copy or move a file or folder, some permissions will be inherited. It is important to know what permissions will be inherited, and what permissions will not. There is a very simple rule to remember that will make this easy. The rule is:
If a new file is created instead of simply moving the existing file then the permissions will not be inherited.
That's it, pretty simple really.
