# Properties

Name-value pairs determine the properties of various parts of the system, such as email, database, network access and more.

## Server properties

Properties that are not in the database, are in files in this folder:

```text
/webapp/WEB-INF/config/
```

> **Note:** These are different to [PSML properties](/psml/elements/element_property.md).

### Private properties

The following folder stores many of the same files as the folder above, but these hold the default values for the system, and must remain under the control of the software. System upgrades overwrite the values in these files, and various aspects of the system rely on these values to correctly function.

```text
/webapp/WEB-INF/sysconfig/
```

> **Warning:** DO NOT MODIFY files under `sysconfig` – the results will be impossible to predict, and expensive to debug.
