What is a TRT file?

TRT files mostly belong to AvaSoft-Basic.

TRT files serve several distinct purposes depending on the software that created them. The most common use is to store spectrometer data from devices by Avantes. In this case, the file may contain sensor readings, calibration details, and other measurement data that are processed with applications like AvaSoft-Basic.
In other scenarios, a TRT file can be a serialized deep learning model used with NVIDIA TensorRT. These files hold optimized neural network engines for GPU inference.
Other observed uses include:

• Spectrometer Data Files – Used to record measurement information (often in binary or text formats) for analysis.
• TensorRT Model Files – Store pre-optimized neural network data for fast inferencing.
• Compressed Archive Files – Some TRT files are ZIP-compressed containers, such as those used by TRT-Player for export functions.
• Game Save Files – Employed by certain games, like Patrician III, to record user progress.
• Template Files – XML-based templates used in software like Integration Builder.

For further details, check out the Avantes AvaSoft page for spectrometer data and the NVIDIA TensorRT site for model files.

FilExt.com tip: If you face issues opening your TRT file, first determine its origin. A text editor may not display binary or compressed formats correctly.

How to open TRT files

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

TRT format details:

Each file has a definite file format, that is, how the stored data is arranged in the file. The file format can be deduced from the file extension and the signature. File extension, signature and file format must match; otherwise errors will occur when the file is opened. If there are problems opening a file, you must first determine the file format used. Our analysis of the TRT files produces the following result:

An TRT file covers different formats for different programs. The following file formats are most commonly found in TRT files:

• 20% of all TRT files start with the bytes M- crucial for this file format. The contents of these files are easily readable with a text editor. TRT files are between 11 KB and 31 KB in size. The file type is very recent. Certain words are almost always found in the files, such as Integration time, Wave   ;Sample, [nm]   ;[counts], Nr of pixels used for smoothing: 0, Average: 1 scans and Data measured with spectrometer serial number: 0312009H1. NEW0001.trt or NEW0002.trt is a typical file name. Files like these are sometimes connected to mikas.
• 7% of all TRT files use the same file format, which can be identified by the letters "110" at the beginning. The contents of these files can even be read by a human. The file size is in the range of 31 KB to 40 KB. The files contain the following words: Integration time, Nr of pixels used for smoothing: 0, Average: 1 scans, Average: 2 scans, Data measured with spectrometer name: 1109090U1 and 1109090U1-. These files are often associated with cathode, mbar and percent.

All other TRT files (73%) have different formats, the following 5 formats exist: GeoTortue project, ptrt and STRUCTURE. They are often associated with aifrep, trait, yolo, trtexport, sample, model or tiny. If you want to find out what your TRT file contains, drag and drop it onto this page.
