SimpleFile

SimpleFile is a Cordova plugin that lets you read and write files from the filesystem.

You can also create/remove directories, extract the URI from a file and download remote content to a file.

It currently features support for Android and iOS.

Install

From the root of a cordova project run:

$ cordova plugin add cordova-plugin-simple-file 

Javascript API

The plugin exposes the window.plugins.simpleFile object. It provides access to different file systems through their corresponding object:

• plugins.simpleFile.internal
  • Private files stored in the app's data folder. The content will not be saved in iCloud
  • On iOS: /var/mobile/Applications/<UUID>/Library/NoCloud
  • On Android: /data/data/<app-id>/files
• plugins.simpleFile.internal
  • Private files stored in the app's data folder. The content will be saved in iCloud.
  • On iOS: /var/mobile/Applications/<UUID>/Library
  • On Android: /data/data/<app-id>/files
• plugins.simpleFile.external
  • On Android, it provides access to the device's SD card. It defaults to the private app storage if no SD card is not present in older devices.
  • On iOS: /var/mobile/Applications/<UUID>/Library/NoCloud
    • iPhones do not have external memory cards. Same as the internal filesystem.
  • On Android: <sdcard>/
• plugins.simpleFile.bundle
  • Files packaged in the app binary (i.e. www)
  • This file system is read only

Reading files

window.plugins.simpleFile.<fs>.read(fileName, successCallback, errorCallback)

Reads the contents of a file and provides them to the given successCallback.

Writing to a file

window.plugins.simpleFile.<fs>.write(fileName, contents, successCallback, errorCallback)

Writes the contents in contents to the path provided in fileName. This function will create any folders in fileName that do not exist yet.

Note: This will not work if you use it with the bundle filesystem.

Removing a file or folder

window.plugins.simpleFile.<fs>.remove(fileName, successCallback, errorCallback)

Removes the file or folder specified in fileName. If fileNameis a folder, all of its contents are removed as well.

Note: This will not work if you use it with the bundle filesystem.

Getting a file's URL

window.plugins.simpleFile.<fs>.getURL(fileName, successCallback, errorCallback)

Provides the URL to reference a file from inside the browser.

Downloading remote files

window.plugins.simpleFile.<fs>.download(url, fileName, successCallback, errorCallback)

Downloads a file and saves the contents to the file specified in fileName. This function will create any folders in fileName that do not exist yet.

Note: This will not work if you use it with the bundle filesystem.

Creating a folder

window.plugins.simpleFile.<fs>.createFolder(dirName, successCallback, errorCallback)

Creates a folder and all the parent directories that do not exist yet.

Note: This will not work if you use it with the bundle filesystem.

Listing folders

window.plugins.simpleFile.<fs>.list(folderName, successCallback, errorCallback)

Provides the successCallback function with an array of objects, containing the files and folders contained inside the folderName directory.

Every object in the array has the following structure:

{
	name: "file.txt",
	isFolder: false
}

To list the root directory, just set folderName to either "" or "."

Copying files or folders

window.plugins.simpleFile.copy(originFilesystem, originFileOrFolder, destinationFilesystem, destinationFileOrFolder, successCallback, errorCallback)

Copies the file or folder (with all its contents) to the given destination.

As an example:

window.plugins.simpleFile.copy('bundle', 'logo.png', 'internal', 'logo.png', successCallback, errorCallback)

General example

The next example copies the phonegap logo to the internal directory and sets that logo.png as the current page of the webView:

window.plugins.simpleFile.bundle.read("www/img/logo.png",function(data) {

	window.plugins.simpleFile.internal.write("logo.png", data, function() {

		window.plugins.simpleFile.internal.getUrl("logo.png", function(url) {
			alert(url);
			window.location.href = url;
		},function(err) {
			alert("ERROR in getUrl: "+err);
		});
	},function(err) {
		alert("ERROR: write: "+err);
	});
},function(err) {
	alert("ERROR: read: "+err);
});
