you get to any file by following the filesystem path whose bytes match the content you are looking for. There's no searching for the content you want.
if you're crawling the filesystem it will probably take you until the heat death of the universe to complete that crawl.
So you get a file. Any file. Not necessarily the file you want, unless you already know its contents and how to traverse the folder hierarchy to get to that specific point.
