Quando se activa (ou desactiva) determinado grupo de permissões isso implica activar (ou desactivar) um conjunto de permissões especiais.
No entanto as permissões especiais podem ser activadas (ou desactivadas) separadamente, não necessitando por isso de activar todas as permissões associadas a determinado grupo de permissões:
| Special permission | Applies only to | Semantics |
| Traverse Folder | Folders | Allows or denies moving through folders to reach other files or folders, even if the user has no permissions for the traversed folders. Traverse folder takes effect only when the group or user is not granted the Bypass traverse checking user right in the Group Policy snap-in. (By default, the Everyone group is given the Bypass traverse checking user right.) |
| Execute File | Files | Execute File allows or denies running program files. Setting the Traverse Folder permission on a folder does not automatically set the Execute File permission on all files within that folder. |
| List Folder | Foldera | Allows or denies viewing file names and subfolder names within the folder. List Folder only affects the contents of that folder and does not affect whether the folder you are setting the permission on will be listed. |
| Read Data | Files | Allows or denies viewing data in files. |
| Read Attributes | Allows or denies viewing the extended attributes of a file or folder. Extended attributes are defined by programs and may vary by program. | |
| Read Extended Attributes | Allows or denies viewing the extended attributes of a file or folder. Extended attributes are defined by programs and may vary by program. | |
| Create Files | Folders | Allows or denies creating files within the folder. |
| Write Data | Files | Allows or denies making changes to the file and overwriting existing content. |
| Create Folders | Folders | Allows or denies creating folders within the folder. |
| Append Data | Files | Append Data allows or denies making changes to the end of the file but not changing, deleting, or overwriting existing data. |
| Write Attributes | Allows or denies changing the attributes of a file or folder, such as read-only or hidden. Attributes are defined by NTFS. The Write Attributes permission does not imply creating or deleting files or folders, it only includes the permission to make changes to the attributes of a file or folder. In order to allow (or deny) create or delete operations, see Create Files/Write Data, Create Folders/Append Data, Delete Subfolders and Files, and Delete. | |
| Write Extended Attributes | Allows or denies changing the extended attributes of a file or folder. Extended attributes are defined by programs and may vary by program. The Write Extended Attributes permission does not imply creating or deleting files or folders, it only includes the permission to make changes to the attributes of a file or folder. In order to allow (or deny) create or delete operations, see Create Files/Write Data, Create Folders/Append Data, Delete Subfolders and Files, and Delete. | |
| Delete Subfolders and Files | Folders | Allows or denies deleting subfolders and files, even if the Delete permission has not been granted on the subfolder or file. |
| Delete | Allows or denies deleting the file or folder. If you do not have Delete permission on a file or folder, you can still delete it if you have been granted Delete Subfolders and Files on the parent folder. | |
| Read Permissions | Allows or denies reading permissions of the file or folder, such as Full Control, Read, and Write. | |
| Change Permissions | Allows or denies changing permissions of the file or folder, such as Full Control, Read, and Write. | |
| Take Ownership | Allows or denies taking ownership of the file or folder. The owner of a file or folder can always change permissions on it, regardless of any existing permissions that protect the file or folder. | |
| Synchronize | Allows or denies different threads to wait on the handle for the file or folder and synchronize with another thread that may signal it. This permission applies only to multithreaded, multiprocess programs. |
