The test is called the "general notability guideline". In short, any topic needs to have at least 2 citations to different sources that meet all of the following requirements:
1. The source provides significant coverage (at least 1-2 sizable paragraphs) of the topic
2. The source is reliable
3. The source is a secondary source that is editorially and financially independent of the subject (and of the other source)

A manual for the file format would not meet requirement #3, since it's a primary source that was published by the company who developed it.
This rule is in place to prevent companies from publishing information about their own products, and then promoting them on Wikipedia in a biased way.
However, it isn't considered an independent source, since it was written by a company with a vested interest in the topic.
To prove that the file type is notable, you'll need at least different 2 sources that meet all 3 requirements: they must provide significant coverage of the topic, be reliable, and be independent of the topic.
You don't have to use these sources to write all of the content in your article, but they do have to be cited as references to pass the notability test.
The three most common kinds of reliable sources are:
- Articles or web pages from a reputable news organization, magazine, or web publisher (with an editorial team)
- Books from a reputable publishing company
- Publications from a peer-reviewed academic journal
Offline and non-English sources are accepted.
If you can't find at least 2 sources that meet these requirements, then the topic doesn't pass the notability test and isn't suitable for Wikipedia. In this case, you're probably better off sharing your article somewhere else, such as Wikibooks, Wikiversity, or your personal blog.
I also find it ironic that Wikipedia notability is so tied to traditional publishing sources.
ADDED: I admit to falling pretty heavily on the inclusionist side; I'm pretty skeptical about notability at times.
"Significant coverage" addresses the topic directly and in detail, so that no original research is needed to extract the content. Significant coverage is more than a trivial mention, but it does not need to be the main topic of the source material.
