What is an LH file

LH files mostly belong to MP4Box. Lecture recordings or game archives?: If your LH file has an MP4 internal format, it is most likely a lecture recording. This variant wraps standard MP4 video data and is usually processed with tools like MP4Box. In such cases, a media player that supports MP4 (for example, VLC) can display the content.
Some LH files are used for game data and compressed archives. For instance:

A file used as a New Super Mario Bros. U level data file (often distributed with Lhaplus) is really a compressed archive.

Other files like the Love Hina compressed archive or a level header file (sometimes labeled LHArc) serve similar functions in game data storage.

To determine which type you have, you might open the file with a hex editor or check its metadata. For compressed archives, software such as Lhaplus or LHarc-based tools are needed. More details on related decompression software can be found at the Lhaplus website.
FilExt.com note: The LH extension is used in more than one context, so verifying the file’s internal structure is key.

How do you open LH files?

You need a suitable software like MP4Box to open an LH file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your LH file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a LH file directly in the browser:. Just drag the file onto this browser window and drop it.
