推荐答案
查看 Cordova File API ，它基于W3C File API。它用于读取，写入和浏览文件系统层次结构。
Take a look at the Cordova File API which is based on the W3C File API. It is used to read, write and navigate file system hierarchies.
列出文件和文件夹
要列出/计数目录中的列表和文件，您必须使用 DirectoryReader 对象。
In order to list/count the lists and files inside a directory you have to use the DirectoryReader object.

例如：
function success(entries) {
var i;
for (i=0; i<entries.length; i++) {
console.log(entries[i].name);
}
}
function fail(error) {
alert("Failed to list directory contents: " + error.code);
}
// Get a directory reader
var directoryReader = dirEntry.createReader();
// Get a list of all the entries in the directory
directoryReader.readEntries(success,fail);
创建目录
要创建目录，您必须使用 DirectoryEntry 对象。此对象包含创建或查找目录的 getDirectory 方法。

document.addEventListener("deviceready", onDeviceReady, false);
// Cordova is ready
function onDeviceReady() {
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, onFileSystemSuccess, onFileSystemFail);
}
function onFileSystemSuccess(fileSystem) {
console.log(fileSystem.name);
var directoryEntry = fileSystem.root;
directoryEntry.getDirectory("newDir", {create: true, exclusive: false}, onDirectorySuccess, onDirectoryFail)
}
function onDirectorySuccess(parent) {
console.log(parent);
}
function onDirectoryFail(error) {
alert("Unable to create new directory: " + error.code);
