+The function `walk()` from the module [`klaw`](https://github.com/jprichardson/node-klaw).
 
 Returns a [Readable stream](https://nodejs.org/api/stream.html#stream_class_stream_readable) that iterates
 through every file and directory starting with `dir` as the root. Every `read()` or `data` event

 recommend this resource as a good starting point: https://strongloop.com/strongblog/whats-new-io-js-beta-streams3/.
 
-#### Filtering the file walker stream
-
-On many occasions you may want to filter files based upon size, extension, etc.
-You should use the module [`through2`](https://www.npmjs.com/package/through2) to easily
-accomplish this.
-
-Example (skipping directories):
-
-first:
-
-    npm i --save through2
-
-
-```js
-var fs = require('fs-extra')
-var through2 = require('through2')
-
-var excludeDirFilter = through2.obj(function (item, enc, next) {
-  if (!item.stat.isDirectory()) this.push(item)
-  next()
-})
-
-var items = [] // files, directories, symlinks, etc
-fse.walk(TEST_DIR)
-  .pipe(excludeDirFilter)
-  .on('data', function (item) {
-    items.push(item.path)
-  })
-  .on('end', function () {
-    console.dir(items) // => [ ... array of files without directories]
-  })
-
-```
