    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 of the File System API represents a file in a file system. It lets you write content to a file.
