# Network The list of available databases is maintained in so-called 'settings.xml' files. These file names all start with 'settings' and end with '.xml'. ### Interactive and OS-Applications A default file 'settings.xml' is placed in the user's home directory folder 'Invantive' during discovery of databases in interactive or OS-applications. Additional settings files may be placed in this folder too. ### Web Applications For web applications, the folder App_Data/Config must contain the settings.xml files. Additional settings files may be placed in this folder too. ### Additional Locations Using the environment variable INVANTIVE_SETTINGS_FILE_PATH, you can specify a different file name and path for the default settings.xml file. Settings.xml is not searched for at other locations. ### Structure The settings files all have the following structure in XML format; The full specification is available in [xsd format](settings.xsd) and [online](https://documentation.invantive.com/2017R2/settings-xml/index.html).
