The Microsoft globbing library supports the following two wildcard characters; `*` and `**` (See https://docs.microsoft.com/en-us/aspnet/core/fundamentals/file-providers#globbing-patterns for more information). * - Matches anything at the current folder level, or any filename, or any file extension.Matches are terminated by / and . characters in the file path. ** - Matches anything across multiple directory levels.Can be used to recursively match many files within a directory hierarchy. Globbing pattern examples: directory/file.txt - Matches a specific file in a specific directory. directory/*.txt - Matches all files with .txt extension in a specific directory. directory/*/bower.json - Matches all bower.json files in directories exactly one level below the directory directory. directory/**/*.txt - Matches all files with .txt extension found anywhere under the directory directory.
