NTFS is a U-disk format we use, in addition to the alignment of the permission settings, NTFS folder also has permission settings. Let's take you today to understand the rules for applying NTFS permissions.

One, the combination of permissions

When a user belongs to more than one group, the user gets the cumulative permissions of each group, and the user's permissions are denied once the appropriate permissions for a group are denied. For example, suppose you have a user Bob, if Bob belongs to A and B two groups, group A has Read permission to a file, B has Write permission to the file, and Bob has permission to modify the file, then Bob's final permission for the file is read + Write + modify.

Ii. Inheritance of permissions

Inheritance means that the newly created file or folder automatically inherits the NTFS permissions of the previous directory or drive, but the permissions inherited from the previous level cannot be modified directly, only to add additional permissions on this basis.

Iii. impact of Move and copy operations on permission inheritance

1, the impact of moving files or folders within the same partition;

2, the impact of copying files or folders within the same NTFS partition;

3. Copying or moving files and folders from an NTFS partition to a FAT partition will cause file and folder permissions to be lost.

Iv. combined permissions for shared permissions and NTFS permissions

The biggest problem with Windows system sharing is that both NTFS and share permissions affect the ability of users to access network resources. There are only three sharing permissions: Read, change, and full control. The default shared files for Windows Server 2008 setting permission is Creator Owner, and without any Read permission, the default shared file setting permission for Windows Server 2003 is everyone, and the user only has Read permissions.

1. READ: Read permission is the default permission assigned to the Everyone group.

2. Change: More permissions are the default permissions for any group. Changing permissions adds the following permissions in addition to allowing all read permissions.

1) Add files and subfolders

2) Change the data in the file

3) Delete Subfolders and files

3. Full Control: Full Control permissions are the default permissions assigned to the Administrator group on this computer. Full Control permissions have change permissions in addition to allowing full Read permissions.

Figure two: NTFS format

Share permissions are valid only for users who access the universal network, so sometimes you need to work with NTFS permissions (if the partition is a FAT file system and the FAT32 file system, you do not need to consider) to strictly control user access. When a shared folder is set to share permissions and NTFS permissions, it is controlled by both permissions. Original Address http://www.ntfsformac.cn/quanxian-guize.html
