What is an MXT file?

MXT files mostly belong to MicroCal Origin. MXT files come in two distinct types.
One common type is a measurement data file produced by scientific instruments. This file is created by MicroCal Origin and holds data from devices such as Avantes spectrometers. It is used to record experimental readings and analysis, and only specific software like MicroCal Origin can fully interpret its proprietary structure.
The other type of MXT file serves as a template file in mapping applications. This version follows the Microsoft Compound Document format and is used within MapInfo Pro to define map layouts and data tables. For further details on this mapping variant, you can visit the related support page.
Key details summarized by FilExt.com:

Measurement files are designed for spectrometer data capture.

Template files aid in map configuration and data exchange.

The internal structure of an MXT file depends on its origin, thus requiring the matching software to open and view it properly.

How to open MXT files

You need a suitable software like MicroCal Origin to open an MXT 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 MXT file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a MXT file directly in the browser:. Just drag the file onto this browser window and drop it.

MXT file format details:

If you know the file format, you can also find out how to open or edit the file. The initial characters of a file are called signature, sometimes also referred to as "magic bytes". The signature can be used to infer the file format. If the file extension or signature does not match the file format, errors will occur when opening or editing the file. Exact knowledge of the format is therefore important in order to solve problems occurring in files. Our analysis of the MXT files produces the following result:

The MXT file extension is not widely used. Such a file mainly uses a special format. The file formats most commonly found in MXT files are:

• 90% of all MXT files start with the bytes SCRIPTY=[, which are crucial for this file format. If you open these files in a text editor, you can view and read the content yourself. Most of these files are 2 KB to 4 KB in size. This file type is new and state-of-the-art. The following keywords are characteristic: CONC, DSEC, SCRIPTY, TEMP, TIME, 900.000, SCRIPTX=[#CVI], 902.000 and SCRIPTX=[#ELE]. Files like these are sometimes connected to htitration, ddmtitration, laser, fmax, ddmtit, sdstit, conduct, ddmtitr, hghsds and umsds.
• 4% of all MXT files use the Microsoft Compound File format, also known as Compound File Binary File format (CFBF or CFB) or OLE2 Compound Document format. Compound document files are used to structure the contents of a document in the file. It is possible to divide the data into several streams, and to store these streams in different places in the file. In this way compound document files support a complete file system inside the file, the streams are like files in a real file system, and the sections are like subdirectories. Compound files always start with the bytes ÐÏࡱá (hex code D0 CF 11 E0 A1 B1 1A E1). These files are binary files, so they do not contain text, but only cryptic characters. MXT files can be up to 6 MB in size, but are often around 130 KB - 2 MB.

All other MXT files (6%) have no consistent format. These files are often connected to buffer, htit, phddmtitration or phddmtit. You can get all the details of your MXT file by dragging it onto this page or by clicking the button "Choose your .mxt file to analyze" above.
