.. title:: FS_MGMT_DL_CHUNK_SIZE

.. option:: CONFIG_FS_MGMT_DL_CHUNK_SIZE

*Maximum chunk size for file downloads*

Type: ``int``

Help
====

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.
