The configuration file count is much larger in V3 compared to earlier versions, partly due to new features, partly because we have created smaller units of configuration dealing with specific tasks, and partly because we've tried to expose more options directly without requiring code changes or plugins. In practice, you should expect to interact with the same files as in earlier versions on a regular basis and you may never touch many of these files.

To help orient you, a summary of the general function of each file follows along with a tip for when or why you might care about it. The order is alphabetic, not based on the frequency of use.

The "RL?" column notes which files can be reloadable, but not necessarily which ones are since that depends on the "checkInterval" properties in services.properties.
