Question

How to rename a directory using JavaScript file system API?

I tried as given below:

dirNameWithPath = '/MyPictures3/New Folder';
newDirName = 'newTitle';
dirPath = '/MyPictures3';

filesystem.root.getDirectory(dirNameWithPath, {}, function(dirEntry) {
    dirEntry.moveTo(dirPath, newDirName, callback, errorHandler);
});

I am getting the following error:

FileError.INVALID_MODIFICATION_ERR

Is that even possible? You might accidentally overwrite some other directory (or fail, gaining knowledge) — John Dvorak

@JanDvorak What not possible? renaming a directory? renaming directory is possible. see html5rocks.com/en/tutorials/file/filesystem. It is not overwriting. — Mohammed H

The first parameter of moveTo must be a DirectoryEntry (not a String):

void moveTo(DirectoryEntry parent,
            optional DOMString newName,
            optional EntryCallback successCallback,
            optional ErrorCallback errorCallback);

The parent parameter is "The directory to which to move the entry".

And "entry" is the directory to be moved/renamed (directory.moveTo(newLocation, newName)).
