+
+## [Usage Documentation](https://ionicframework.com/docs/native/file/)
+
+Plugin Repo: [https://github.com/apache/cordova-plugin-file](https://github.com/apache/cordova-plugin-file)
+
+This plugin implements a File API allowing read/write access to files residing on the device.
+
+The File class implements static convenience functions to access files and directories.
+
+Example:
+
+```
+import { File } from '@awesome-cordova-plugins/file/ngx';
+
+constructor(private file: File) { }
+
+...
+
+this.file.checkDir(this.file.dataDirectory, 'mydir').then(_ => console.log('Directory exists')).catch(err =>
+  console.log('Directory doesn't exist'));
+
+```
+
+This plugin is based on several specs, including : The HTML5 File API http: //www.w3.org/TR/FileAPI/
+The (now-defunct) Directories and System extensions Latest: http: //www.w3.org/TR/2012/WD-file-system-api-20120417/
+Although most of the plugin code was written when an earlier spec was current: http:
+//www.w3.org/TR/2011/WD-file-system-api-20110419/ It also implements the FileWriter spec : http:
+//dev.w3.org/2009/dap/file-system/file-writer.html
