What is a CAP file?
A CAP file contains packets collected by a packet sniffing program. It saves raw data and metadata captured over a network transmission. CAP files are also called trace files or bone files, and they are used by multiple packet sniffer applications.
Using a CAP file, you can examine and analyze the data passed between devices on a digital network. Network administrators and other IT professionals use CAP files to:
- Analyze and diagnose network problems
- Detect malicious network activity
- Maintain compliance with certain IT regulations
How do I open a CAP file?
You can open a CAP file using Wireshark, a free-to-download packet sniffing program available for Windows and Mac PCs.

What is a CAP file?
A CAP file is a musical score created using Capella, a music composition program. It contains binary or XML data that Capella translates into notes, rests, measures, and other musical notation. The CAP file format was replaced by the .CAPX format.
Capella is a Windows and Mac program that composers use to create, edit, play, and print musical scores. In previous versions of Capella, these scores were saved as CAP files.
Originally, CAP files were binary files that could be opened only in Capella and its related software, such as Capella Viewer. However, around the year 2008, the Capella team began transitioning the program to save scores in an open XML format, so composers could load Capella scores in other composition programs. During this transition period, some CAP files were saved in an XML format. So, a CAP file may contain either binary or XML data, depending on when it was created. Now, the CAP file format has been replaced by the CAPX format, which is an entirely XML-based format.
How do I open a CAP file?
You can open a CAP file in Capella (Windows, Mac), Capella Reader (Windows, Mac), or Capella Score Reader (iOS, Android). Capella Reader and Score Reader are free programs that allow composers to view, play, and print the score a CAP or CAPX file contains.
