'''<player>.dat''' files are used by [[Minecraft:server]]s to store the state of individual [[Minecraft:player]]s. The format is also used within [[Minecraft:Java Edition level format#level.dat format|level.dat]] files to store the state of the [[Minecraft:singleplayer]] player, which overrides any <player>.dat files with the same name as the singleplayer player. These files are in [[Minecraft:NBT format]].

Items are used both in the player's inventory and ender chest.

The image below shows the slot numbers of the player's inventory slots as of [[Minecraft:Java Edition 1.21.5]].

== Trivia ==
* Pre-1.7.10 player data files were named as the player's username rather than their UUID, this meant if the server was running on Windows and the player had a reserved filename as a player name they would not have their player data saved. List of Reserved Windows Filenames:
** <code>AUX</code>
** <code>COM<n></code> where n is a digit from 1-9 (inclusive)
** <code>CON</code>
** <code>LPT<n></code> where n is a digit from 1-9 (inclusive)
** <code>NUL</code>
** <code>PRN</code>
