Good lord ... does this guy got an issue or something ....

Sarick you need to stop your making yourself look VERY stupid right now.

Inventory is stored on the server not on your PC. When you go to open a new inventory device that list is then downloaded. This is know to anyone who's used a latent checker before.

Temp items are just bit flags as someone else has already said. That means 1 bit per item, for 50 items your looking at 7 bytes of memory give or take, and that's for ALL temp items as their unique to each zone.

Now you may continue with your evil SquareEnix tin foil hat theory, but the reasoning has been known for a long time.
