############################

*Maximum chunk size for file downloads*

Type: ``int``

Help
====

.. code-block:: none

    Sets the MAXIMUM size of chunk which will be rounded down to
    number of bytes that, with all the required headers, will fit
    into MCUMGR_BUF_SIZE. This means that actual value might be lower
    then selected, in which case compiler warning will be issued.
    Look inside fs_mgmt_config.h for details.
    Note that header sizes are affected by FS_MGMT_MAX_OFFSET_LEN.
