Robocopy wildcard ignores leading period

Hello,

I came across this as I was making a custom procedure to sync our roaming folders (yes we still need them!), as this feature has been a bit shaky in W11.

In the root of a user home, there's a few NTUSER-related files,

NTUSER.DAT

ntuser.dat.LOG1

ntuser.dat.LOG2

NTUSER.DAT{...

and so on. 

Even though I think that it's best to leave all these files alone, while playing around with wildcards I noticed that it was impossible(?) to get

/XF "ntuser.dat.*" 

to match only ntuser.dat.LOG1 and ntuser.dat.LOG2, it swallowed NTUSER.DAT as well. Only if I matched on 

/XF "ntuser.dat.L*

did it leave NTUSER.DAT alone. 

Surely this is not intended behavior? Or does the dot have an undocumented function in relation to wildcards?

Best regards

Alexander
