From get-help about_wildcards:
Windows PowerShell supports the following wildcard characters.
Wildcard Description Example Match No match

? Matches exactly ?n an, in, on ran one character in the specified position
[ ] Matches a range [a-l]ook book, cook, look took of characters
[ ] Matches specified [bc]ook book, cook hook characters
[ and ] are special characters.
