<h2 id="overview">Overview</h2>
<p>Local File System Access (LFSA) is:</p>
<ul>
<li>a tiny web server to allow client side JS access to local file system</li>
<li>a buildling block for Client Side Web Apps (CSWA)</li>
<li>a single Python file</li>
</ul>
<h2 id="cswa">CSWA</h2>
<p>Client Side Web Apps run solely on your device, they are not related to cloud solutions in any way: nobody can pull the plug on you.
CSWAs use LFSA to keep data at your hard drive, so you have complete control of your data.</p>
<p><a href="http://opengamestudio.org/pskov">PSKOV</a> static site generator is the first CSWA to use LFSA.</p>
<h2 id="install">Install</h2>
<p>If you use Linux or macOS released after 2005 (yes, 2005), you only need to <a href="../lfsa-201905.py">download lfsa-201905.py</a>.</p>
<p>If you use Windows 2000 or newer (excluding Windows ME), you need to:</p>
<ul>
<li><a href="https://www.python.org/downloads/windows/">download</a> and install Python 2.3 or newer</li>
<li><a href="../lfsa-201905.py">download lfsa-201905.py</a></li>
</ul>
<h2 id="run">Run</h2>
<p>If you use Linux or macOS, run LFSA in Terminal this way:</p>
<pre><code>/path/to/lfsa-201905.py /path/to/dir
</code></pre>
<p>Here's how it looks like on macOS Mojave:</p>
<p><img src="../img/lfsa-on-macos.png" alt="LFSA on macOS Mojave" /></p>
<p>If you use Windows, run LFSA in <a href="https://en.wikipedia.org/wiki/Cmd.exe">CMD</a> this way:</p>
<pre><code>C:/path/to/Python/installation/python.exe C:/path/to/lfsa-201905.py C:/path/to/dir
</code></pre>
<p>Here's how it looks like on Windows 2000:</p>
<p><img src="../img/lfsa-on-windows.png" alt="LFSA on Windows 2000" /></p>
<h2 id="durability">Durability</h2>
<p>As you noticed, LFSA can run on really old operating systems dating back to 2000. That's intentional: we care about users, so we want to cover as many users as possible.</p>
