Copying NTFS Security Descriptors
Beyond Compare 4, 3, 2.3 or newer
Windows 2000 or better
Beyond Compare provides an option to copy NTFS security descriptors. With it enabled, any of Beyond Compare's copy commands (copy, copy to folder, move, move to folder, and sync commands) will copy security descriptors of files on NTFS file systems under Windows 2000 or newer. This option does not preserve permissions of files saved in the File Viewer.
BC version 3 or 4
In a Folder Compare or Folder Sync session, select Session Settings from the Session menu. Go to the Handling tab. Check Copy NTFS file permissions (requires admin rights).
BC version 2
To enable the copying of NTFS security descriptors, create a DWORD registry key named
HKEY_CURRENT_USER\Software\Scooter Software\Beyond Compare\Settings\CopyACLs.
Setting the value to 1 will enable the feature, 0 will disable it.
Handling of Inheritance
Files and folders are copied as normal. After each file or folder is copied, the security descriptor (owner, group, dacl, sacl) is copied. If the source file (or folder) is set to inherit permissions from its parent, non-inherited permissions are copied and inheritable permissions from the parent on the target side are inherited. If the source file is set to block permissions from its parent, permissions are copied from the source and no permissions are inherited from the target parent.
Known Issue - Folders with read only permissions
The current implementation does a simple copy of security descriptors immediately after a file or folder is copied. If the folder being copied denies write access to the logged on user, Beyond Compare will copy the folder, set the deny permissions on it, and then fail to copy the contents of the folder.
Known Issue - Non-Windows NAS devices
Non-Windows network attached storage (NAS) device compatibility with Beyond Compare's Copy NTFS file permissions setting varies by manufacturer and firmware version. If the setting is enabled but NTFS permissions fail to copy, updating NAS device firmware will sometimes resolve the issue.
