SOLVED
Hello,
I'm following the documentation for creating Files in the Asset database from here: http://developers.marketo.com/rest-api/assets/files/#create_and_update
So I'm using a images and files folder, and trying to create a new file (it currently has no files).
I copy and pasted the body given by the documentation under Create
With the following header:
I'm getting "File is mandatory".
Is there something else I'm missing?

You'd highlight that code as Plain (as MIME isn't a supported syntax) like so:
Which turns it into:
------WebKitFormBoundary2VyWOacQSupl4gUL
Content-Disposition: form-data; name="file"; filename="marketo.html"
Content-Type: text/html
<html>
<body>
<h1>Test Page - marketo.html</h1>
</body>
</html>
------WebKitFormBoundary2VyWOacQSupl4gUL
Content-Disposition: form-data; name="name"
marketo.html
------WebKitFormBoundary2VyWOacQSupl4gUL
Content-Disposition: form-data; name="folder"
{"id":436,"type":"Folder"}
------WebKitFormBoundary2VyWOacQSupl4gUL
Content-Disposition: form-data; name="description"

The #set() syntax is literal Velocity/Java code. It's not part of using the hightlighter.
Now we can look at the payload properly and see there are several things wrong with it.
First, this boundary is incorrect for your payload (this is exactly why a monospace font is used for code):
multipart/form-data; boundary=------WebKitFormBoundary2VyWOacQSupl4gUL
You have 6 hyphens:
------WebKit...
And your actual MIME parts also have 6 hyphens, which is incorrect:
------WebKit...
In the body, you want 8 hyphens, the constant prefix of -- followed by the boundary.
Second, after the final boundary, you need to have an additional suffix -- (you have an em-dash there instead).
Third, you need to have a line break (CRLF) after the header section of each MIME part.
So the correct format is:
--------WebKitFormBoundary2VyWOacQSupl4gUL
Content-Disposition: form-data; name="file"; filename="marketo.html"
Content-Type: text/html
<html>
<body>
<h1>Test Page - marketo.html</h1>
</body>
</html>
--------WebKitFormBoundary2VyWOacQSupl4gUL
Content-Disposition: form-data; name="name"
marketo.html
--------WebKitFormBoundary2VyWOacQSupl4gUL
Content-Disposition: form-data; name="folder"
{ "id":1187, "type":"Folder" }
--------WebKitFormBoundary2VyWOacQSupl4gUL
Content-Disposition: form-data; name="description"

Can you please paste actual code using the Advanced Editor's syntax highlighter? Troubleshooting a screenshot is really... suboptimal.

Cool, hopefully others will find this thread instead of copying the code examples from the docs. 
I assume maybe an editor (not an coder) stripped out the all-important line breaks to save space and didn't know hyphens are special...
