Where is storage_path('/app/public/') located

I want to run my code via command where i placed a file in folder app/public/results

And i want to access this file with this code:

if ( ! File::exists(storage_path('/app/public/examResult/' . $this->argument('file'))) ) {dd('Not found this file!');}

But its printing not found this file.

Where are these files actually stored where code can find them ?
