Mac File Permissions
NTFS is the standard file system of the Windows NT operating system family. Starting with Windows NT 4.0 Service Pack 6, it supported the concept of permissions which can be configured to permit or restrict access to files, folders, and other objects locally and over a network.
Permissions
By default, almost all system files, system folders and even Registry keys in Windows 10 are owned by a special built-in user account called 'TrustedInstaller'. Other user accounts are set to only read the files.
As a user accesses each file, folder, registry key, printer, or an Active Directory object, the system checks its permissions. It supports inheritance for an object, e.g. files can inherit permissions from their parent folder. Also every object has an Owner which is the user account that can set ownership and change permissions.

If you are interested in managing NTFS permissions, refer to the following article:
Permission types
In short, there are two types of permissions - explicit permissions and inherited permissions.
There are two types of permissions: explicit permissions and inherited permissions.
Explicit permissions are those that are set by default on non-child objects when the object is created, or by user action on non-child, parent, or child objects.
- Inherited permissions are those that are propagated to an object from a parent object. Inherited permissions ease the task of managing permissions and ensure consistency of permissions among all objects within a given container.
By default, objects within a container inherit the permissions from that container when the objects are created. For example, when you create a folder called MyFolder, all subfolders and files created within MyFolder automatically inherit the permissions from that folder. Therefore, MyFolder has explicit permissions, while all subfolders and files within it have inherited permissions.
Effective permissions are based on a local evaluation of the user's group membership, user privileges, and permissions. The Effective Permissions tab of the Advanced Security Settings property page lists the permissions that would be granted to the selected group or user based solely on the permissions granted directly through group membership.
By resetting effective permissions, you will restore NTFS permissions of files and folders back to their default inherited permissions.
Quickly Reset NTFS Permissions in Windows 10
To reset NTFS Permissions in Windows 10, do the following.
- Open an elevated command prompt.
- Run the following command to reset permissions for a file:
icacls 'full path to your file' /reset. - To reset permissions for a folder:
icacls 'full path to the folder' /reset. - To reset permissions for a folder, its files, and subfolders, run the command
icacls 'full path to the folder' /reset /t /c /l.
Substitute the example paths with the actual values matching your system.
Here are some screenshots.

When you first create a share point, Mac OS X Lion Server assigns it standard POSIX permissions for Owner, Group, and Others. You can change the owner and group, change the permissions for all three entities, and add users. Standard POSIX permissions are easier to set than ACLs and may be all that you need.
For share points shared with AFP and/or SMB, you can also add permissions with an access control list (ACL) for a finer degree of access control. An ACL is the server’s list of all permissions for all users and groups and for a share point. You add names of users and groups to the list and then use pop-up menus to assign permissions.
ACLs are more complicated than POSIX permissions because they give you up to 17 choices: 13 permissions grouped by type, as well as 4 types of inheritance.
With almost 100,000 possible combinations of ACL permissions, it’s best to set permissions for groups and add user permissions only for exceptions.
These ACL permissions settings are well hidden in the Server app. Here’s how to access them in the Server app:
1Click the name of your server.
You will find it in the sidebar under Hardware.
2Click the Storage tab.
Browse for and select a shared folder.
3Click the gear icon and select Edit Permissions from the pop-up menu.
A list of users and groups appears.

4If you want to add a user or group, click the Add (+) button.
Type the name of an existing user or group.
5To configure permissions, click the triangle to the left of the user or group name.
This exposes the first level of ACL permissions. You have four choices: Administration, Read, Write, and Inheritance. You can make choices here. A hyphen [–] in a check box means that some, but not all, of the subordinate items for that category are selected. Selecting or deselecting a check box selects or deselects all of the subordinate items.
6(Optional) Click the triangles next to the choices to expand them.

This will let you go even deeper into ACL permissions. Make any changes that you need and click ok when done.
An application is a type of file that you can share. If you do, set permissions so that very few people can change permissions for shared applications. In the ACLs, under Administration, few people should have the Change Permissions and Change Owner permissions. Malware such as viruses often targets permissions in applications.
