Old vs New plots

I started plotting a while ago before the new “NFT” plots appeared. When they appeared I started to NFT plot immediately, but I still have the old plots for hpool until I fill the disks that I have and after that I’ll replace them.
In the mean time I encountered such a problem: if I have the old and the NFT plots on the same disk and I want to avoid double plotting when I have Chia gui and hpool opened simultaneously, how can I know that a plot is OG or NFT, so I can separate them?
Thanks for any help.

How to distinguish original OG plots from new portable plots?


I tried the search function, but I admit I’m a bit noob cuz didn’t find anything. Thanks!
