{{exclusive|java}}

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

== NBT structure ==

{{:Player/ED}}

== Item structure ==
{{Main|Data component format}}

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

== Inventory slot numbers ==

In Minecraft Java version 1.20.1 equip slots have these numbers - Offhand 40, Head 39, Chest 38, Legs 37, Boots 36.

[[File:Items slot number.png|alt=This shows the numbers used to specify the slot in the inventory while editing with an NBT editor.]]

== 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>
