2.3. Configuration¶
All configuration files used by PyMoDAQ will be located within a folder named pymodaq_local saved by default on the user Home folder (see Fig. Fig. 2.4)

Fig. 2.4 Local folder to store configuration files¶
2.3.1. Configs from Managers¶
Each folder contains dedicated files: the log as text file and all module configuration files as xml files. These files are generated by dedicated managers when the user is configuring one aspect of PyMoDAQ, for instance using the Preset manager for defining Actuators and Detectors in the Dashboard. Apart the log, a user should not interact directly with those but use their respective manager user interface to create and modify them.
2.3.2. Default configuration¶
The config.toml file is the only exception. It is there so that a particular user could enter specific personal information such as the name that will be used by default in the metadata, default preset file to load if executing directly the DAQ_Scan extension, default type of Scan and so on. The file can be directly modified or accessed within the Dashboard in the file menu.
