Web/API/FileSystemEntry/moveTo

This is an experimental technologyCheck the Browser compatibility table carefully before using this in production.

ObsoleteThis feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

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

FileSystemEntry.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 succesfully 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

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.

Example

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

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