Disable player.dat saving / creating

Should I disable the storing of player .dat files? Each player file takes around 2 kB, means that when my server has 1.000.000 players, then it will take 4 GB... too much. Btw whats the usage of these files and is your player.dat storing disabled?

The player.dat file stores general player data, such as inventory, location, health, and other personal attributes.
If you disable player.dat saving, you'll need to find some other way to retain their data.

Ah thx, I think I can delete it because I have a minigame server.

you could by using a plugin who delete then every shutdown or something
but i believe there better methods
