Using the asterisk and a question mark in the filter is called file globbing. File globbing is the
processing of pattern matching using wildcards. The wildcards are officially called
metacharacter wildcards. You can use more metacharacter wildcards for file globbing than
just the asterisk and question mark. You can also use brackets
