I want the best way to organize tons of items so players can save in the inventory

I think Item ID, serializing with ItemID, names are waste of space, but should I make a lot of folders or like 1 folder with every item

The way I have is a folder with every item in the game, and inside is a module script with all the info on the item, including an ItemID.

Can you please explain further, like snap a pic
