.HDML File Extension
What is an HDML file?
The .HDML file extension stands for Handheld Device Markup Language, which was a markup language used to create content for handheld devices, primarily mobile phones in the late 1990s and early 2000s. It was designed to enable developers to create content and applications specifically for devices with limited screen sizes and capabilities.
More Information.
HDML emerged as a precursor to more advanced mobile web technologies. Its main purpose was to provide a way to display web-like content on mobile phones and other handheld devices with limited hardware and display capabilities. It allowed for the creation of simple, text-based content and basic navigation on these devices.
Origin Of This File.
HDML was developed by a company called Openwave (formerly known as Phone.com) in the late 1990s. It was part of an early push to standardize how content was delivered to mobile devices before the widespread adoption of WAP (Wireless Application Protocol) and XHTML.
