Formula of Files

Searching for a pattern known,
I look at the numbers shown,
I know it exists with an exponential amount,
A formula of files that I try to count,
Groups within a descending array,
Mathematically ascending the opposite way,
It is a mere illusion with a simple pattern,
Binary numbers, will others count them?
A path to follow to arrive at the destination,
I probably created it for need of a vacation,
I tried to confuse to keep something safe,
To make it special in a hidden place,
So now I’ve tried to explain,
I feel this is all very simple & plain.
