The ownCloud Client reads a configuration file.  You can locate this configuration file as follows:

On Linux distributions:
        ``$HOME/.local/share/data/ownCloud/owncloud.cfg``

On Microsoft Windows systems:
        ``%LOCALAPPDATA%\ownCloud\owncloud.cfg``

On MAC OS X systems:
        ``$HOME/Library/Application Support/ownCloud/owncloud.cfg``


The configuration file contains settings using the Microsoft Windows .ini file
format. You can overwrite changes using the ownCloud configuration dialog.

.. note:: Use caution when making changes to the ownCloud Client configuration
   file.  Incorrect settings can produce unintended results.

Some interesting values that can be set on the configuration file are:
