<removed>This article contains outdated/incorrect information.</removed> The structure of the Lua folder can be confusing. Here's a rundown: &lt;ul&gt;&lt;li&gt; **lua** &lt;ul&gt;&lt;li&gt; **autorun** - all files are automatically loaded on Lua start. &lt;ul&gt;&lt;li&gt; **client** - autorun client scripts. &lt;/li&gt;&lt;li&gt; **server** - autorun server scripts. &lt;/li&gt;&lt;li&gt; **shared** - autorun shared (both cl_ and sv_) scripts. &lt;/li&gt;&lt;/ul&gt;⤶ &lt;/li&gt;&lt;li&gt; **includes** - init.lua loaded on start. &lt;ul&gt;&lt;li&gt; **enum** - Loaded on start. Contains all enum files. &lt;/li&gt;&lt;li&gt; **extensions** - Loaded on start. Extends existing libraries and types. &lt;/li&gt;&lt;li&gt; **modules** - Contains all modules. &lt;/li&gt;&lt;/ul&gt;⤶ &lt;/li&gt;&lt;li&gt; _**downloaded** - Clientside downloaded files &lt;ul&gt;&lt;li&gt; **.cache** - Contains cached versions of all downloaded files (to prevent constantly redownloading) &lt;/li&gt;&lt;/ul&gt;⤶ &lt;/li&gt;&lt;li&gt; **postprocess** - Run by client on startup &lt;/li&gt;&lt;/ul&gt;⤶ <ul><li> **lua** <ul><li> **autorun** - all files are automatically loaded on Lua start. <ul><li> **client** - autorun client scripts. </li><li> **server** - autorun server scripts. </li><li> **shared** - autorun shared (both cl_ and sv_) scripts. </li></ul>⤶ </li><li> **includes** - init.lua loaded on start. <ul><li> **enum** - Loaded on start.
