<p>The <b>Minix file system</b> is the native <a href="File_system" title="File system">file system</a> of the <a href="Minix" title="Minix">Minix</a> <a href="Operating_system" title="Operating system">operating system</a>. It was written by <a href="Andrew_S._Tanenbaum" title="Andrew S. Tanenbaum">Andrew S. Tanenbaum</a> in the 1980s and aimed to replicate the structure of the <a href="Unix_File_System" title="Unix File System">Unix File System</a> while omitting complex features, and was intended to be a teaching aid. It largely fell out of favour among Linux users by 1994 due to the popularity of other filesystems - most notably <a href="Ext2" title="Ext2">ext2</a> - and its lack of features, including limited partition sizes and filename length limits.

<p>MINIX was written by <a href="Andrew_S._Tanenbaum" title="Andrew S. Tanenbaum">Andrew S. Tanenbaum</a> in the 1980s, as a <a href="Unix-like" title="Unix-like">Unix-like</a> operating system whose source code could be used freely in education. The MINIX file system was designed for use with MINIX; it copies the basic structure of the <a href="Unix_File_System" title="Unix File System">Unix File System</a> but avoids any complex features in the interest of keeping the source code clean, clear and simple, to meet the overall goal of MINIX to be a useful teaching aid.<sup id="cite_ref-TanenbaumOSBook_1-0" class="reference"><a href="#cite_note-TanenbaumOSBook-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup>
</p><p>When <a href="Linus_Torvalds" title="Linus Torvalds">Linus Torvalds</a> first started writing his <a href="Linux" title="Linux">Linux</a> operating system kernel (1991), he was working on a machine running MINIX, and adopted its file system layout. This soon proved problematic, since MINIX restricted filename lengths to 14 characters (30 in later versions), it limited <a href="Disk_partitioning" title="Disk partitioning">partitions</a> to 64 megabytes,<sup id="cite_ref-Strobel_2-0" class="reference"><a href="#cite_note-Strobel-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> and the file system was designed for teaching purposes, not performance.<sup id="cite_ref-Mauerer_3-0" class="reference"><a href="#cite_note-Mauerer-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> The Linux implementation of the MINIX fs was multi-threaded, whereas the MINIX implementation of the fs was single-threaded.<sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> The <a href="Extended_file_system" title="Extended file system">extended file system</a> (ext; April 1992) was developed to replace MINIX's, but it was only with the second version of this, <a href="Ext2" title="Ext2">ext2</a>, that Linux obtained a commercial-grade file system.<sup id="cite_ref-Mauerer_3-1" class="reference"><a href="#cite_note-Mauerer-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> As of 1994, the MINIX file system was "scarcely in use" among Linux users.<sup id="cite_ref-Strobel_2-1" class="reference"><a href="#cite_note-Strobel-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup>

<p>A MINIX file system has six components:<sup id="cite_ref-TanenbaumOSBook_1-1" class="reference"><a href="#cite_note-TanenbaumOSBook-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup>

<ul><li>The <a href="Boot_sector" title="Boot sector">Boot Block</a> which is always stored in the first block. It contains the <a href="Booting" title="Booting">boot loader</a> that loads and runs an <a href="Operating_system" title="Operating system">operating system</a> at system startup.</li>
<li>The second block is the <b>Superblock</b> which stores data about the file system, that allows the operating system to locate and understand other file system structures. For example, the number of <i>inodes</i> and <i>zones</i>, the size of the two bitmaps and the starting block of the <i>data area</i>.</li>
<li>The <b>inode <a href="Bitmap" title="Bitmap">bitmap</a></b> is a simple <a href="Map_(computer_science)" class="mw-redirect" title="Map (computer science)">map</a> of the <a href="Inode" title="Inode">inodes</a> that tracks which ones are in use and which ones are free by representing them as either a one (in use) or a zero (free).</li>
<li>The <b>zone bitmap</b> works in the same way as the <i>inode bitmap</i>, except it tracks the zones.</li>
<li>The <b>inodes</b> area. Each file or directory is represented as an inode, which records metadata including type (file, directory, block, char, pipe), IDs for user and group, three timestamps that record the date and time of last access, last modification and last status change. An inode also contains a list of addresses that point to the zones in the <i>data area</i> where the file or directory data is actually stored.</li>
<li>The <b>data area</b> is the largest component of the file system, using the majority of the space. It is where the actual file and directory data are stored.</li></ul>
