.CAP File Extension

Contains packets collected by a packet sniffing program; saves raw data captured over a data transmission; also called a trace file or bone file and is used by multiple packet sniffer applications.

BIOS update file used to "flash" the BIOS to ASUS computers running Windows; contains settings and instructions for updating the BIOS on an ASUS motherboard.

BIOS stands for "Basic Input/Output System" and is a type of firmware used by a computer's microprocessor to boot the computer system when it is turned on. It is also used to manage the data flow between a computer's operating system and any attached devices.

NOTE: To update the BIOS on your computer, download the CAP file from the ASUS website and copy it to a USB key (formatted to FAT or FAT 32). Then, connect it to the appropriate ASUS machine, and use the EZ Flash utility (built into the BIOS firmware) to load the update.

Project file created by Construct, a game development application used for building DirectX games; includes game graphics, audio, physics models, and event handlers for actions in the game.

NOTE: Construct now uses .CAPX and .CAPROJ files for game development projects.

A CAP file contains an experiment created by PASCO Capstone, a scientific program used to collect, display, and analyze data in engineering and physics labs. It stores information about an experiment, which may include one or more pages of analyses and graphs, calculations, collected data, and experiment settings.

Capstone CAP experiment files are saved in a proprietary format and can only be opened using PASCO Capstone in Windows or macOS. To open a CAP file in Capstone follow these steps:

1. Select File → Open Experiment....
2. Navigate to the location of the CAP file and select it.
3. Click Open.

NOTE: Capstone CAP files are used for storing experiments in various scientific fields, such as thermodynamics, oscillations, mechanics, quantum, electromagnetism, and waves and optics.
