MIME types
MIME is a standard that classifies resources and provides information (to programs) about how to handle them. This allows the correct handling and interpretation of different type files by programs (like browsers). For example, thanks to MIME, browsers can open correctly a ".txt" file as a plain text resource and not as a video stream or other type.When a MIME type is not specified for a resource, the handling program can "guess" it from the resource's extension (e.g., a file with the ".bmp" extension is supposed to contain a bitmap image). But this may not always give good results as a file extension may be asociated to more than one format. On the other hand, MIME types are unique. This is the main reason why MIME types should be defined everywhere possible.
In HTML documents, authors can use MIME types in many instances, usually through the "type" attribute. Some special cases of its use are with the "enctype" attribute in the HTML form element, and when defining the document's "content-type" in the HTML meta tag.
