The manila folder is a holder designed to contain documents and paperwork. It is generally formed by folding a large sheet of stiff card in half. Though traditionally beige, sometimes other colors are used to differentiate categories of files.

The manila component of the name comes from manila hemp or abaca, from which manila folders were originally made. Manila hemp is a type of fiber that comes from a relative of the banana plant. Commonly used for ropes, paper products, and coarse fabrics, manila hemp is indigenous to the Philippines and gets its name from the country's capital.

Someone that’s so bland, vapid, and empty in the head that they can only serve as a tool to put things in. They can also lack personality, but it’s not a requirement for classification. Usually referring to a person of the whitest of heritages, but can be of any heritage (especially if they have a colonialist mentality)
Most of the comments I’ve seen defending Trump on social media are written by Manila Folders that couldn’t compose a complete sentence to save their lives.
