title: Where is the location of the mime plugin files in mac and linux?
body: <p>I was just curious as to how mime types were read/interpreted by local applications including the browser. Are the plugins for reading the mime type build into each application, or is there a special system folder in the OS that the application refers to when interpreting a mime type?</p>
  <p><a href="https://www.rfc-editor.org/rfc/rfc2045" rel="nofollow noreferrer">RFC</a> uses the character-charts as references when defining what a MIME type is:</p>
  <blockquote>
  <p>(1)   textual message bodies in character sets other than
  US-ASCII</p>
  </blockquote>
  <p>Although <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/MIME_types" rel="nofollow noreferrer">MDN</a> makes it sound like it uses the <code>content-type</code> you would find in things like HTML</p>
  <p>Does something like <code>content-type=image/jpeg</code> or <code>content-type=application/javascript</code> use the UTF-8 char chart to determine their charsets (The glyph) while something else does the logic to determine what those char glyphs should be interpreted into?</p>
  <p>OR does this mean that each content-type has their own special charchart (like utf-8 -&gt; js-8????) that does both glyph conversion of character and logic interpretation of char glyph into binary?</p>
  <p>Why does it sound like charcharts and content-type both mean MIME?
  Where is the folder path for both Mac and Linux systems containing content-type charts / interpretation logic?</p>
