What Is a Glob?
Two methods in the Files class accept a glob argument, but what is a glob?
You can use glob syntax to specify pattern-matching behavior.
A glob pattern is specified as a string and is matched against other strings, such as directory or file names. Glob syntax follows several simple rules:
Two asterisks, **, works like * but crosses directory boundaries. This syntax is generally used for matching complete paths.
I couldn't figure out ** filter.Could you give me an example ?
Thanks.
