-	Using this flag implies that the client is making large sequential reads and/or writes

-	
-	The flag gives a hint to the file server and filesystem to adjust to a streaming
-	data pattern and try their best to make it optimal.
-	
-	Some conditions apply:
-	- This does not guarantee that the performance of read/write operations will increase.
-	- Using this flag for other purposes other than data streaming may lead to performance degradation.
-	- This may sacrifice user data integrity for the sake of performance.
-	
-	If a file is opened by Client A with EFileSequential, and the file is then opened
-	without EFileSequential by Client B, then this file mode will be disabled.
-	When the file handle is closed by Client B, then the EFileSequential file mode
-	will be enabled again.
-	Therefore, this mode will only be enabled if all clients set the file as such,
-	otherwise the file mode will be disabled.
-	
-	FAT file system specific information:
-	This flag improves write and file expansion performance whilst decreasing robustness
-	on a "Rugged-FAT" file system, which is applicable to internal non-removable drives.
