So the UNIX INFO2 call both FindFirst and Query have support for these fields. In the Samba Docs at http://wiki.samba.org/index.php/UNIX_Extensions#SET_CIFS_UNIX_INFO.

4	108	ULONG	FileFlags	File flags enumeration
4	112	ULONG	FileFlagsMask	Mask of valid flags
If the client is doing a set with the UNIX_INFO2 level and it does not want to alter the FileFlags, it should provide a FileFlagsMask of 0.
The defined set of file flags is
File Flag	Value	Interpretation
EXT_SECURE_DELETE	0x00000001	File should be erased such that the data is not recoverable
EXT_ENABLE_UNDELETE	0x00000002	File should opt-in to a server-specific deletion recovery scheme
EXT_SYNCHRONOUS	0x00000004	I/O to this file should be performed synchronously
EXT_IMMUTABLE	0x00000008	NO changes can be made to this file
EXT_OPEN_APPEND_ONLY	0x00000010	Only appends can be made to this file
EXT_DO_NOT_BACKUP	0x00000020	Backup programs should ignore this file
EXT_NO_UPDATE_ATIME	0x00000040	The server is not required to update the last access time on this file
EXT_HIDDEN	0x00000080	User interface programs may ignore this file



We only care about the EXT_IMMUTABLE, EXT_HIDDEN and EXT_DO_NOT_BACKUP(reverse  of the DOS Archive Bit)

Set Query UNIX Info2 allow us to set these values.
