Item Manager (FIXED & UPDATED)

@echo off

:: This is a fixed version of Item Manager. The prompts that are given a file name instead of the provided options
:: used to crash Item Manager. This was fixed, and now crashing from inputing file names is pretty much non existant.
:: I also made it so that the option of examining items happens when you input a file name in the :d flag.

:: If the folder that will contain all the lists doesnt exist, then it will create one for you.
