Save Minecraft Plugin Inventories?

I wanted to ask how best to store inventories between. I mean that I can read this again at any time and load.

I can help you with that, but it would be cool if we could talk about TS, Discord or even Skype (it would make it a lot easier).

If you are interested you can contact me.

Naturally. I have discord. My name: Entity303 # 2079

So you have two main options:
• A File
• SQL (as ByteArray in a Blob)

If you need help: TheSaltyOne # 8410

I wanted to do it with a file. I do not really know how to write in the inventory there. Previous attempts either did not work or did not work completely

Well. Should it be readable? So for you? Or just be saved and reloaded?

It should only be saved and loaded
