What is a VI2 file

VI2 files mostly belong to Testo ComSoft Basic. These VI2 files are internal file formats used by Testo data loggers. They rely on the Microsoft Compound structure to store measurement data from test equipment.
Inside a VI2 file, data is organized into multiple streams that hold measurement values, calibration settings, and system logs.

Data logging: The file holds detailed test measurements and instrument logs.

Software compatibility: It is specifically designed for viewing and analysis with Testo ComSoft Basic or Testo Saveris 2.

Compound file structure: The format allows the file to contain multiple components in a single container.

A *.VI2 file is a data logger file primarily associated with Testo data logging devices and software. It stores measurement data recorded by these devices, often environmental parameters like temperature and humidity. The internal structure of *.VI2 files is a proprietary format called Microsoft Compound File, indicating it's based on Microsoft's structured storage technology. These files are commonly used with Testo ComSoft Basic software for analyzing and managing the logged data. While primarily used with Testo ComSoft Basic, *.VI2 files might also be compatible with other Testo software, such as Testo Saveris 2, which offers advanced data management and reporting capabilities. This file format is classified as Data file.

VI2 file extension format:

Every file has a defined file format, i.e. how the data is arranged in the file. The file format can be deduced from the file extension and the signature. Frequently, however, one file extension is used by different programs for different file formats, and one file format for different file extensions. Exact knowledge of the format is therefore important in order to solve problems occurring in files. In the following you will find our evaluation of the VI2 files:

The VI2 file type is a very commonly used file extension and is mainly used by one program with a specific format. The two most popular formats are as follows:

97% of all VI2 files are based on the Microsoft Compound File format, which is also called Compound File Binary File format (CFBF or CFB) or OLE2 Compound Document format. This file format is used by previous Microsoft Office programs and other Windows programs and stores the data in complex containers and sections. Header signature for the CFB format with 8-byte Hex value D0CF11E0A1B11AE1 (which looks like "DOCFILE"). The unique Windows component object identifier is 1ca5c76a-1906-40f3-9eae-5482fdd74edb or f90137e0-4964-11d3-a4fa-d3b81383c40a. Sections and streams in the file are named org. The files are on average 25 KB in size and range from 5 KB to 130 KB. The file type is relatively new. Files like these are about testo, logger, temperaturmessung, data, temp, datenlogger, hlschrank, frigo and lager.
1% of all VI2 files use the same file format, which have the signature 47 1F 4C 36 48 57 97 9C 91 8D 4D 57 49 48. These are binary files, so they do not contain words or text. VI2 files are between 450 KB and 2 MB in size. The keywords L6HW are typical for these files.

All the rest of the VI2 files (2%) have different formats. They are often associated with enregistreur, enceinte, room, registrador, datalogger, messung, nevera, grand, kopie, sonde or juin.
