About MTH files

The .MTH file extension is primarily used to store method and parameter settings for high-end scientific instruments. It is notably used by the TA Instruments DMA Q800 for dynamic mechanical or thermal analysis, and the Agilent MassHunter Workstation. These files dictate how complex hardware executes a specific laboratory test. The .MTH extension is also used by Texas Instruments Derive for mathematical data, and by Nintendo's Super Smash Bros. Melee to store game movie replay data.

The main disadvantage of .MTH files is that they are highly proprietary. Instrument method files require expensive, specialized software suites - often tied to a physical hardware license - just to view or modify the parameters. Users often need to convert these files into TXT, CSV, or PDF to share testing protocols with colleagues or auditors who do not have the original instrument software installed. Similarly, game movie .MTH files are not actual video recordings; they are lightweight files that record controller inputs. Because they do not contain pixel data, they cannot be directly converted to standard video formats like MP4 or MKV without using screen recording software while the game engine renders the replay.

Because these files are closed-source and strictly bound to specific hardware or game engines, standard online converters fail to process them. They lack standard document or media headers. However, just drag and drop your file into convert.guru to identify the format, view it, and convert it when possible. Our analysis tools can inspect the raw data - and since some .MTH instrument files use UTF-16 (LE) text encoding - we can often show you the embedded text, allowing you to extract readable test parameters even without the original proprietary software.

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.


FAQ

If you want to convert MTH file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use Agilent MassHunter or similar software from the "Instrument Analysis Method Settings" 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 Agilent MassHunter or another comparable tool in the "Instrument Analysis Method Settings" category.



The MTH Converter Story

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.
