Would a flat file structure allow for faster locating/fetching of files by Path in an NTFS (Windows 10 File System) or would it essentially be as efficient as a highly structured tree with a bunch of subfolders? I'm using node.js to fetch a few hundred million locally stored JSON files and I'd prefer a tree-like file structure, but I want to make sure that wouldn't be less efficient than a flatter file structure and less depth/nested folders.
I'd like to know if Google Cloud Storage provides an efficient way of checking if a file with a given name exists in a given bucket with node.js. A method such as bucket.fileExists('someName') would be ideal. I apologize if there's an obvious answer. Any constructive feedback would be greatly appreciated.
