FileSystemEntry.remove()

This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The FileSystemEntry interface's method remove() deletes the file or directory from the file system. Directories must be empty before they can be removed.

To recursively remove a directory as well as all of its contents and its subdirectories, call FileSystemDirectoryEntry.removeRecursively() instead.

Syntax

JavaScript
FileSystemEntry.remove(successCallback[, errorCallback]);

Parameters

successCallback
A function which is called once the file has been successfully removed.
errorCallback Optional
An optional callback which is called if the attempt to remove the file fails.

Return value

undefined.

Errors

FileError.INVALID_MODIFICATION_ERR
The specified entry was the file system's root directory, or the specified entry is a directory which isn't empty.
FileError.INVALID_STATE_ERR
The file system's cached state is inconsistent with its state on disk, so the file could not be deleted for safety reasons.
FileError.NO_MODIFICATION_ALLOWED_ERR
The file system's state doesn't permit removing the file or directory.
FileError.NOT_FOUND_ERR
The file or directory doesn't exist.
FileError.SECURITY_ERR
The entry couldn't be removed due to permissions or other access constraints, or because there are too many calls being made on file resources.

Example

This example deletes a temporary work file.

JavaScript
workingDirectory.getFile("tmp/workfile.json", {}, function(fileEntry) {
  fileEntry.remove(function() {
    /* the file was removed successfully */
  });
}, handleError);
