You caught me, Dan. Absolutely right. Zero or more. I’m assuming there is
a brilliant discussion of this somewhere in the IFS Kit documentation, of
course (right Diane? 
)

Hi Tony,
* = “match one or more characters”
I believe that should read “zero or more”.

There are five wildcard characters in the Windows pattern matching
syntax (that is the syntax implemented by FsRtlIsNameInExpression, that
venerable and nearly inscrutable function.)
* = “match one or more characters”
? = “match one character”
< = “match one or more characters using MS-DOS semantics”
= “match one character using MS-DOS semantics”
" = “match dot using MS-DOS semantics”
Thus, the last three are for MS-DOS compatibility, which restricts the
character set that can match. For example, spaces are allowed in MS-DOS
names, but not before or after the dot. These MS-DOS patterns match
those semantics.
For building your own strings, I highly recommend sticking with the
Windows semantics, not the MS-DOS semantics.

Tony

Don’t wanna bother, but for (3) I have some additional questions.
The format of “*.doc” is really easy to use (especially when building
directory information buffers), but how about those special wildcards
like “"” or “<” ( C notation, it’s hard to quote a " 
) ? Is there an
overview of all options for directory wildcards and their meaning
somewhere? Or can one simply use * for any illegal non-zero character?
Regards & TIA,
Tobias
