What is a CWA file?

CWA files mostly belong to CWA-FileReader. This file is an Actigraph raw data file that stores unprocessed sensor readings from activity monitoring devices. It contains binary information captured from accelerometers used in research and motion analysis.
Key Details provided by FilExt.com:

Raw Sensor Data: The file holds continuous, high-frequency accelerometer measurements.

Embedded Metadata: Additional information (like time stamps) is stored to help with data analysis.

Proprietary Format: The structure is optimized for performance in data logging and research settings.

The file is typically generated by devices from BuisDataLogger and is best viewed with specialized software such as CWA-FileReader. For additional details and support, you can visit the related webpage at GaitUP.
Usage: This file is primarily used in activity research, gait analysis, and sensor data processing. It should be opened and interpreted using its dedicated viewer rather than a general text editor.

How to open a CWA file

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

CWA file extension format:

Each file has a definite file format, that is, how the stored data is arranged in the file. A file format is determined by the file extension and signature, so JPEG images have the extension .jpg and the first bytes in the file are ÿØÿ. If the file extension does not match the file format, double-clicking on the file will cause an error upon opening. When there is a problem with a file, the first step to solving it is to determine the file format. Below is our analysis of the CWA files:

CWA is seldom used as a file extension and is mainly used by one program with a specific format. But the following two file formats are common:

• 80% of all CWA files are Continuous Wave Accelerometry data files. They consist of illegible, cryptic characters. Most of these files are 560 KB to 260 MB in size. The file type is very old but is also used today. Examples of file names are CWA-DATA.CWA or longitudinal_data.cwa. Such CWA files store data about data, longitudinal and accsamp.
• 2% of all CWA files are C-Worthy Form files. If you open these files in a text editor, you can view and read the content yourself. The files are often between 24 KB and 24 KB in size.

The remaining 18% of all CWA files are different files with different signatures. Drag & drop your file here to see the file format and a preview of your CWA file!
