FileSystemEntry: moveTo() method
================================

**Deprecated:** This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

**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
 **`moveTo()`** moves the file
 specified by the entry to a new location on the file system, or renames the file if
 the destination directory is the same as the source.

 There are some typical
 restrictions on what you can do:

* A directory can't be moved into itself.
* An entry can't be moved into its parent directory unless you specify a new name.
 Specifying a new name lets `moveTo()` double as a rename operation.
* When moving a directory, the move is always recursive; you can't leave out
 subfolders.
* You can't move a file such that it replaces an existing directory, and you can't
 move a directory such that it replaces an existing file. However, a file can replace a
 file and a directory can replace a directory.
* You can only overwrite a directory if it's empty.
Syntax
------


```js
moveTo(newParent, newName)
moveTo(newParent, newName, successCallback)
moveTo(newParent, newName, successCallback, errorCallback)
```

### Parameters

`newParent`

 A `FileSystemDirectoryEntry` object specifying the destination
 directory for the move operation.


`newName` Optional

 If this parameter is provided, the entry is renamed to have this string as its new
 file or directory name.


`successCallback` Optional

 A function which is called when the move operation is successfully completed.
 Receives a single input parameter: a `FileSystemEntry` based object
 providing the moved item's new details.


`errorCallback` Optional

 An optional callback which is executed if an error occurs while moving the items.
 There's a single parameter: a `FileError` describing what went wrong.


### Return value

None (`undefined`).

### Errors

`FileError.INVALID_MODIFICATION_ERR`

 The requested operation involves an impossible change, such as moving a directory
 inside itself or one of its own child directories, or copying an item within the same
 directory without renaming it.


`FileError.QUOTA_EXCEEDED_ERR`

 The operation exceeded the user's storage quota, or there isn't enough storage space
 left to complete the operation.


Examples
--------

 This example shows how a temporary log file might be moved into a more permanent "log"
 directory when it exceeds a megabyte in size.


```js
workingDirectory.getFile(
  "tmp/log.txt",
  {},
  (fileEntry) => {
    fileEntry.getMetadata((metadata) => {
      if (metadata.size > 1048576) {
        workingDirectory.getDirectory(
          "log",
          {},
          (dirEntry) => {
            fileEntry.moveTo(dirEntry);
          },
          handleError,
        );
      }
    });
  },
  handleError,
);
```
