Where is the location for old WhatsApp database? In my internal memory, I found the WhatsApp database folder, but it only contains a few files, a maximum of 6/7 days.

Where can I find my old WhatsApp database files? Where would I get the previous days' or months' chat database?
if you start what's app without restoring previous data it gets deleted and if you are talking about encryption you can eaisly access it by scanning the qr code in other device
