What is a .HDM file?
The file extension .HDM is associated with HDML files, which stand for Handheld Device Markup Language files. These files are essentially web pages, but they're specifically crafted for use on small, portable electronic gadgets like smartphones and Personal Digital Assistants (PDAs). Unlike regular web pages that we see on computers, which use HTML (HyperText Markup Language) and are transferred over the internet using HTTP (HyperText Transfer Protocol), HDML files are designed to be more suitable for the smaller screens and limited capabilities of handheld devices. To get these files onto such devices, a different protocol called HDTP (Handheld Device Transport Protocol) is used instead of HTTP.
If you come across an .HDM file and you need to open or edit it, you can do so using a simple text editor. Text editors are basic software tools that allow you to view and modify the text-based content of files. Examples of text editors include Notepad on Windows, TextEdit on macOS, and Gedit on Linux. Since HDML files are coded in a markup language, they are essentially text files, and thus, can be opened and edited with any text editor. When you open an HDML file in a text editor, you'll see the code that defines the structure and content of the web page intended for handheld devices. This might include text, links, and instructions on how the page should look when displayed on a device's screen.
In summary, .HDM files are HDML files used for creating web pages for handheld devices. They are transferred using a special protocol called HDTP and can be opened and edited with any basic text editor available on your computer.
