FileError was removed from File API ( after Chrome shipped the feature. This surfaces on: FileReader.error, FileWriter.error, and in the FileSystem API passed to the ErrorCallback (async) and thrown (sync) Other browsers do not use this, returning DOMError instead, which is itself being deprecated in favor of DOMException. The interface has been deprecated since 2013. In Chrome 53 we're adding a console warning. Removal is anticipated in Chrome 54.
