This column becomes important when we have the same users assigned to different groups, and we want to deny some actions for that users on particular file or folder.
The top box shows the users or groups with existing permissions for the folder. When we select a user, the bottom box shows the permissions of that user or group. In this case the parent is the E drive.
In our case, the parent object is the E drive. Administrators have full control because they need to manage the drive and its contents. By default all files and folders are configured to inherit permissions from the parent object. When we do that, we are given a choice. We can either copy the existing permissions or we can completely remove them. After the copy is finished, we can change the existing permissions. If the existing permissions are completely wrong, we could just remove them and build our own permissions from scratch.
Notice that we have the same permissions list as we had before. But this time we can edit the permissions. Otherwise the permissions will be inherited from the parent. When we add new user or group to the ACL, we can assign the permissions for that user or group of users as we desire.
Our users can belong to more than one group, so this option comes in handy in that case. In this case we will add the privileges up. After completing that process, you're ready to turn off the Simple File Sharing interface and reveal the more complex Security tab, with its full array of NTFS permissions. Switching back and forth indiscriminately can wreak havoc with network shares.
If you normally use Simple File Sharing, but occasionally need to work with the full set of permissions, you can bypass the dialog boxes with this simple script, which toggles between the two modes. Open Notepad or any plain text editor and enter the following text:. Create a shortcut to the script and add it to the All Programs menu; for even faster access, assign a keyboard shortcut to the script.
This is a dramatic improvement over Simple File Sharing, which allows you to protect files in your user profile only. Allow different types of access for different users or groups of users. For instance, you might allow your teenagers read-only access to your collection of digital music files, so that they can play them but not erase them to make room for their own downloaded tunes. This limitation only applies to the local machine. NTFS doesn't have this restriction. These features include increased fault tolerance and enhanced security.
Also new in this version is the ability to do a quick-format during Windows XP setup. There are a number of other improvements, some of which I'll mention later in this article.
Fault Tolerance. NTFS repairs hard disk errors automatically without displaying an error message. It then checks the file to make sure it matches the copy stored in memory. If the copies don't match, Windows marks that section of the hard disk as bad and won't use it again Cluster Remapping. Windows then uses the copy of the file stored in memory to rewrite the file to an alternate location on the hard disk. If the error occurred during a read , NTFS returns a read error to the calling program, and the data is lost.
NTFS has many security options. You can grant various permissions to directories and to individual files.
