+# Maintain Directory Structure while Globbing
+
+If you are planning to read a few files/folders from a directory and maintain their relative path, you need to pass `{base: '.'}` as the second argument to `gulp.src()`.
+
+
+For example, if you have a directory structure like 
+
+![Dev setup](https://cloud.githubusercontent.com/assets/2562992/3178498/bedf75b4-ec1a-11e3-8a71-a150ad94b450.png)
+
+and want to read only a few files say
+
+```js
+[ 'index.html',
+ 'css/**',
+ 'js/**',
+ 'lib/**',
+ 'images/**',
+ 'plugin/**'
+ ]
+```
+
+In this case, Gulp will read all the sub-folders of (_say_) `css` folder and arrange them relative to your root folder and they will no longer be the sub-folder of `css`. The output after globbing would look like

+
+If you want to maintain the structure, you need to pass `{base: '.'}` to `gulp.src()`. Like
+
+```js
+gulp.task('task', function () {
+   gulp.src(['index.html', 
+             'css/**', 
+             'js/**', 
+             'lib/**', 
+             'images/**', 
+             'plugin/**'
+             ], {base: '.'})
+       .pipe(operation1())
+       .pipe(operation2());
+});
+```
+And the input to your `operation1()` will be a folder structure like 
+
