What is a HMT file?
A .HMT file can belong to several different software programs. Most commonly, it is a font thumbnail cache image created by High-Logic software. These specific files store image data internally using the standard JFIF format. A .HMT file can also be a MainType font metadata file formatted as a PLIST. Additionally, it can be a HighMAT File developed by Microsoft and Panasonic for optical disc content. Other uses include media library metadata files for Archos portable media players, PVR recording metadata files for Humax devices, and DVD project title information for Pinnacle Studio.
How to open HMT files?
Because the .HMT extension has multiple possible meanings, we recommend using viewer.online/hmt to identify the actual format of your file. Our platform analyzes .HMT files to identify their exact format and creator software, shows which programs can open the file, and usually previews it directly in your web browser.
Best practices and troubleshooting
If you use a Humax PVR, the .HMT file pairs directly with your recorded video files. Deleting it will remove title and recording information. If you want to extract the image from a font thumbnail cache, we recommend file conversion to sensible target formats on convert.guru. You can easily convert these .HMT files to standard .JPG or .PNG images.
Summary
The .HMT extension serves many purposes across different hardware and software systems. However, because .HMT files use the known JFIF format, viewer.online/hmt can safely open and display them online, eliminating compatibility problems.
