The ``DataLogManager`` class ([Java](https://github.wpilib.org/allwpilib/docs/development/java/edu/wpi/first/wpilibj/DataLogManager.html), [C++](https://github.wpilib.org/allwpilib/docs/development/cpp/classfrc_1_1_data_log_manager.html), :external:py:class:`Python <wpilib.DataLogManager>`) provides a centralized data log that provides automatic data log file management. It automatically cleans up old files when disk space is low and renames the file based either on current date/time or (if available) competition match number. The data file will be saved to a USB flash drive in a folder called ``logs`` if one is attached, or to ``/home/lvuser/logs`` otherwise.

.. note:: USB flash drives need to be formatted as FAT32 to work with the roboRIO. NTFS or exFAT formatted drives will not work.

Log files are initially named ``FRC_TBD_{random}.wpilog`` until the DS connects. After the DS connects, the log file is renamed to ``FRC_yyyyMMdd_HHmmss.wpilog`` (where the date/time is UTC). If the :term:`FMS` is connected and provides a match number, the log file is renamed to ``FRC_yyyyMMdd_HHmmss_{event}_{match}.wpilog``.
