You can throw billions of bytes of data in there, but without a system, you will never find anything again.</p> <p>A <strong>filesystem</strong> is the specific set of rules, data structures, and &ldquo;ledgers&rdquo; (like the Inodes and Superblocks we discussed) used to organize, index, and retrieve that data. It dictates how large a file can be, how folders are nested, and how permissions are handled.</p>
