Do you want some pictures of it?\n\n.dat isn't a common extension in the base engine, but maybe those files belong to a mod. .dat is often a really generic three letter combination that could be all sorts of things. Tell us all of the filenames, and try to run a program that tells you about what type of file they are, like GNU File (available on Linux, or in packages like Git Bash, Homebrew, Cygwin, or Windows Subsystem for Linux) or TrID.\n\nOne would usually expect 4 databases: auth.sqlite, map.sqlite, mod_storage.sqlite and players.sqlite. However, that goes for singleplayer on the defaults; multiplayer servers often use PostgreSQL for the world, which (if applicable) you hopefully have received in a format that unpacks into directories.\n\nSome background reading\n\n  * World format\n  * Database Backends\n\n\n\nStatistics: Posted by Blockhead — Fri Mar 06, 2026 14:43\n\n* * *",
