Files

Data Folder

config.xml ... stores settings.
npvr.db3 ... SQLite database that stores device, EPG and recording information.

NextPVR Server stores all of the values set in the Settings Web App and all lists of Recordings and all EPG data and everything else in npvr.db3 and config.xml. NextPVR Server can be reset to defaults by deleting npvr.db3 and config.xml. NextPVR Server will recreate npvr.db3 and config.xml with default values when restarted ... typically by rebooting the computer.

Logs folder

nrecord.log ... most recent log from NextPVR Server.
*.1, *.2, *.3 ... preceding logs from NextPVR Server.
device-*.log ... logs from processes that connect to tuner devices

The messages in log files are cached and written to the file on disk at intervals. Viewing the content of a "in progress" log file might not show the latest log messages. You can flush the cache to the file on disk by making a log zip file at Settings -> About.
