2. An SMB2 file name MUST conform to the following guidance:

The rules and error behaviors described above will be added
to [MS-SMB] and [MS-SMB2]. We are finalizing the changes to the
documents and will post them when they are available. Please
don’t hesitate to let us know if you think that more information is
needed.
So I would like to clarify some things here. So when we make a
SMB2_Query_Info Request with a SMB2_0_INFO_FILESYSTEM infotype and
request a FileFsAttributeInformation Vista returns a
MaximumComponentNameLength value of 255.
The [MS-FSCC] doc says the following:
"MaximumComponentNameLength: A 32-bit signed integer that contains
the maximum file
name component length, in bytes, supported by the specified file
system. The value of this
field MUST be greater than 0. "
So now for my questions:
1. Is the MaximumComponentNameLength bytes or characters (Looks like
characters)?
2. So if each element in the path must be no more than 255 characters,
then why do we need MaximumComponentNameLength? Will
MaximumComponentNameLength every be bigger than 255? Seems to me
MaximumComponentNameLength should determine the max element in the
path not 255?
