Extract text from cache and metadata files (HMT)
To convert HMT cache files to another format, you need High-Logic MainType or other Data software.
To convert other file formats to the "Application Cache and Metadata" file type, you need software like High-Logic MainType or a similar tool.
An .HMT file is highly fragmented, serving primarily as a font thumbnail cache for High-Logic MainType or as an obsolete media playlist. For font cache files, the internal structure is actually a standard JFIF raster image. Other common variations include Apple Property List (.PLIST) metadata for fonts, HighMAT disc content files developed by Microsoft and Panasonic, and proprietary PVR recording metadata for Humax set-top boxes and Archos media players.
The main disadvantage of the .HMT format is its extreme fragmentation and proprietary nature. Because multiple companies used the exact same extension for completely different purposes, your operating system cannot natively open it. HighMAT files are tied to dead early-2000s CD/DVD technology, while Humax and Archos files are strictly locked to legacy hardware devices. Without the specific parent application or hardware, the files are effectively dead data.
To make this data usable, conversion is necessary. For visual extraction, convert High-Logic thumbnail caches to JPG or PNG for web and image viewer compatibility. For metadata and property lists, convert to XML or TXT to make the underlying code readable.
Convert.Guru analyzes your HMT file, detects the exact format, and lets you read the text inside.
Users also converted MHT, HIGHMAT, HTM, DECLARATION, HTML, MHTML, PLAYLIST, EPUB, PDF, DOCX and XML files.
If you want to convert HMT file to MP3, WAV, AAC, FLAC, OGG, WMA, M4A, AIFF, OPUS, ALAC, APE or WV, you can use High-Logic MainType or similar software from the "Font Cache & Metadata Storage" category. In the File menu, look for Save As… or Export….
To convert MIDI, AAC, TTA, AU, WV, DTS, MID, FLAC, RA, MP3, PCM or WAV files to HMT, try High-Logic MainType or another comparable tool in the "Font Cache & Metadata Storage" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our HMT converter.
