+- __isDirectory__: Always false. _(boolean)_
+- __name__: The name of the `FileEntry`, excluding the path leading to it. _(DOMString)_
+- __fullPath__: The full absolute path from the root to the `FileEntry`. _(DOMString)_
+
+__NOTE:__ The following attribute is defined by the W3C specification,
+but is _not_ supported:
+
+- __filesystem__: The file system on which the `FileEntry` resides. _(FileSystem)_
+
+Methods
+-------
+
+- __getMetadata__: Look up metadata about a file.
+- __setMetadata__: Set metadata on a file.
+- __moveTo__: Move a file to a different location on the file system.
+- __copyTo__: Copy a file to a different location on the file system.
+- __toURL__: Return a URL that can be used to locate a file.
+- __remove__: Delete a file.
+- __getParent__: Look up the parent directory.
+- __createWriter__: Creates a `FileWriter` object that can be used to write to a file.
+- __file__: Creates a `File` object containing file properties.
+

+-------------------
+
+- Android
+- BlackBerry WebWorks (OS 5.0 and higher)
+- iOS
+- Windows Phone 7 and 8
+- Windows 8
+
+getMetadata
+----------------
+
+Look up metadata about a file.
+
+__Parameters:__
+
+- __successCallback__: A callback that is passed a `Metadata` object. _(Function)_
+- __errorCallback__: A callback that executes if an error occurs when retrieving the `Metadata`. Invoked with a `FileError` object. _(Function)_
+
+__Quick Example__
+
+ function success(metadata) {
+ console.log("Last Modified: " + metadata.modificationTime);
+ }
+
+ function fail(error) {
+ alert(error.code);
+ }
+
+ // Request the metadata object for this entry
+ entry.getMetadata(success, fail);
+
+setMetadata
+----------------
+
+Set metadata on a file.
+
+__Currently works only on iOS.__
+- this will set the extended attributes of a file.
+
+__Parameters:__
+
+- __successCallback__: A callback that executes when the metadata is set. _(Function)_
+- __errorCallback__: A callback that executes when the metadata is not successfully set. _(Function)_
+- __metadataObject__: An object that contains the metadata's keys and values. _(Object)_
+
+__Quick Example__
+
+ function success() {
+ console.log("The metadata was successfully set.");
+ }
+
+ function fail() {
+ alert("There was an error in setting the metadata");
+ }
+
+ // Set the metadata
+ entry.setMetadata(success, fail, { "com.apple.MobileBackup": 1});
+
+__iOS Quirk__
+
+- Only the `com.apple.MobileBackup` extended attribute is supported. Set the value to `1` to prevent the file from being backed up to iCloud. Set the value to `0` to re-enable the file to be backed up to iCloud.
+
+__Quick Example__
+
+ function setFileMetadata(localFileSystem, filePath, metadataKey, metadataValue)
+ {
+ var onSetMetadataWin = function() {
+ console.log("success setting metadata")
+ }
+ var onSetMetadataFail = function() {
+ console.log("error setting metadata")
+ }
+
+ var onGetFileWin = function(parent) {
+ var data = {};
+ data[metadataKey] = metadataValue;
+ parent.setMetadata(onSetMetadataWin, onSetMetadataFail, data);
+ }
+ var onGetFileFail = function() {
+ console.log("error getting file")
+ }
+
+ var onFSWin = function(fileSystem) {
+ fileSystem.root.getFile(filePath, {create: true, exclusive: false}, onGetFileWin, onGetFileFail);
+ }
+
+ var onFSFail = function(evt) {
+ console.log(evt.target.error.code);
+ }
+
+ window.requestFileSystem(localFileSystem, 0, onFSWin, onFSFail);
+ }
+
+ setFileMetadata(LocalFileSystem.PERSISTENT, "Backups/sqlite.db", "com.apple.MobileBackup", 1);
