Extract text from Method or replay files (MTH)
To convert MTH files to another format, you need TA Instruments Orchestrator or other Data software.
To convert other file formats to the "Scientific Method File" file type, you need software like TA Instruments Orchestrator or a similar tool.
The .MTH extension creates a unique challenge because it serves two completely unrelated industries: scientific research and competitive gaming. In the scientific realm, an .MTH file is typically a "Method" file generated by TA Instruments thermal analysis software (like Orchestrator or Universal Analysis) or Agilent MassHunter Workstation. These files act as a recipe for laboratory hardware, containing strict proprietary parameters - such as temperature ramps, frequency sweeps, and data collection intervals - used to run Dynamic Mechanical Analysis (DMA) or other thermal tests. They are not designed to be opened outside the specific instrument control software, which often requires expensive licensing and dongles. Users frequently need to convert these to PDF or TXT simply to archive the experimental conditions or share the method parameters with colleagues who do not have the analysis software installed.
Alternatively, if the file originates from a gaming context, it is likely a replay file for Super Smash Bros. Melee. Unlike a standard video file, this .MTH file contains only the input data (controller commands) required for the game engine to re-enact a match. You cannot play this file in VLC or upload it to YouTube directly. To view it, the match must be rendered within an emulator or the original game engine. Users dealing with this format often look to convert the playback into a standard MP4 or AVI video file for sharing on social media, a process that usually requires screen capture tools rather than a direct file conversion.
Convert.Guru analyzes your MTH file, detects the exact format, and lets you read the text inside.
Users also converted MHT, VTX, ARB and FMA files.
If you want to convert MTH file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use TA Instruments Orchestrator or similar software from the "Instrument Configuration Method" category. In the File menu, look for Save As… or Export….
To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to MTH, try TA Instruments Orchestrator or another comparable tool in the "Instrument Configuration Method" 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 MTH converter.
