Web/API/FileSystemEntry/copyTo

ObsoleteThis feature is obsolete.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 copyTo() copies the file specified by the entry to a new location on the file system. There are some typical restrictions on what you can do:

A directory can't be copied into itself.
An entry can't be copied into its parent directory unless you specify a new name.
When copying a directory, the copy is always recursive; you can't leave out subfolders.

Syntax

FileSystemEntry.copyTo(newParent[, newName][, successCallback][, errorCallback]);

Parameters

newParent: A FileSystemDirectoryEntry object specifying the destination directory for the copy operation.
newName Optional: If this parameter is provided, the copy is given this string as its new file or directory name.
successCallback Optional: A function which is called when the copy operation is succesfully completed. Receives a single input parameter: a FileSystemEntry based object providing the copied item's new details.
errorCallback Optional: An optional callback which is executed if an error occurs while copying 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.

workingDirectory.getFile("tmp/log.txt", {}, function(fileEntry) {
  workingDirectory.getDirectory("log", {}, function(dirEntry) {
    fileEntry.copyTo(dirEntry);
  }, handleError);
}, handleError);
