About 2B files

The .2b extension refers to two distinct, highly specialized file formats that often confuse users due to their proprietary nature.

1. TS-TouchWin Pro HMI Project (Primary)

The most common .2b file is a project source file used by TS-TouchWin Pro (often associated with Xinje industrial controllers) for designing Human Machine Interface (HMI) touch panels. Internally, this file is a ZIP container holding configuration data, interface assets, and logic.
The Problem: These files are strictly intended for industrial development. They cannot be opened by standard text editors, web browsers, or Microsoft Excel, despite occasional misidentification. Users often receive them from engineers and find themselves locked out without the specific manufacturing software.
The Solution:

For Editing: You must use TS-TouchWin Pro. There is no third-party editor.
For Asset Extraction: Since the internal structure is ZIP, you can rename the file from .2b to .zip and extract it using 7-Zip or WinRAR. This allows you to recover embedded images or configuration XMLs without the original software.
For Documentation: Open the project in the native software and use the "Print to PDF" feature to create a shareable PDF of the interface logic.

2. CNSA Level-2B Scientific Data

Less frequently, a .2b file is a scientific data product from the China National Space Administration (CNSA) Ground Application System. These are typically binary datasets representing processed satellite telemetry or remote sensing data.
The Problem: These are raw binary streams that require specific scientific parsing tools or HDF viewers.
The Solution: Convert these to HDF5 or CSV using CNSA-provided toolkits for analysis in MATLAB or Python.

Convert.Guru analyzes your 2B file, detects the exact format, and lets you read the text inside.

The 2B 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 2B converter.
