There are many provided methods for reading and writing files, traversing the filesystem and finding files by matching globbing patterns. Many of these methods are wrappers around built-in Node.js file functionality, but with additional error handling, logging and character encoding normalization.

    Describe: Is the given path a plaintext file? Returns a boolean.

file.listdir(dir, callback)

    Describe: List directories within a directory.

file.glob(pattern [, rootdir])

    Describe: Get the pattern matched files, default root dir is cwd

file.expand(patterns [, options])

    Describe: Return a unique array of all file or directory paths that match the given globbing pattern(s).

    Return: {array} matche files

    Return: {string}

file.mkdir("/tmp/dir", 755)

file.mkdirTemp([dirname] [, mode])
