FileEntrySync
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 FileEntrySync interface represents a file in a file system. It lets you write content to a file.
Warning: This interface is deprecated and is no more on the standard track. Do not use it anymore. Use the File and Directory Entries API instead.
