The MIME type application/vnd.hhe.lesson-player indicates that the file is intended for lesson delivery.

Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQs
What is a .les file and how do I open it?
A .les file is a data file used by the HHE Lesson Player to deliver interactive educational content. To open it, you must have the HHE Lesson Player software installed on your computer, as standard media players cannot interpret the proprietary format.
Can I convert a .les file to MP4 or PDF?
Direct conversion is rarely possible because .les files often contain interactive elements (like quizzes or navigation) that do not translate to static documents or linear video. Your best option is to use screen recording software to capture the lesson playback as a video file.
Why won't my computer recognize the .les file extension?
This usually happens if the HHE Lesson Player is not installed or if the file association is broken. You can try reinstalling the software or manually associating the .les extension with the player application in your operating system settings.
What is the correct MIME type for serving .les files?
The standard MIME type for these files is application/vnd.hhe.lesson-player. If you are hosting these files on a server for download, ensure this type is configured correctly so browsers handle the file appropriately. You can learn more at mime-type.com.
How do I edit the content inside a .les file?
The .les format is typically a compiled output intended for playback, not editing. To change the text, images, or audio within the lesson, you would generally need access to the original authoring tool used to create the course, rather than the player itself.
Are .les files compatible with Mac or Linux?
Compatibility depends entirely on the availability of the HHE Lesson Player for those operating systems. If a native version does not exist, you may need to use Windows emulation software (like Wine or Parallels) to run the player and view the file.
General FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.
Why can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
