What is a UHTML file?

UHTML files mostly belong to UC Browser. A *.UHTML file stores a cached web page, primarily used by the UC Browser. It serves as an offline archive of the web page, allowing users to view content without an active internet connection. The file format is proprietary to UC Browser and contains the rendered HTML, along with other resources like images and scripts, enabling offline browsing. These files are automatically generated by the browser when a user visits a webpage, and they are typically stored in a designated cache directory on the user's device. This caching mechanism allows for faster loading times when revisiting the same page and enables offline access. The internal structure of a *.UHTML file is not publicly documented and is specific to the UC Browser's internal workings.
