Extracting Cabinet Files Using Command Line Tools

Cabinet files, commonly known as `.cab` files, are compressed archives used to package multiple files together, often for software installation or system updates. When installing or extracting a `.cab` file, command line tools provide a powerful and flexible method, especially useful for automation or troubleshooting.

One of the primary tools used in Windows for handling cabinet files is `expand.exe`. This utility allows you to extract files from `.cab` archives without requiring a graphical interface. The basic syntax for extracting files is:

“`
expand [source.cab] -F:* [destination_folder]
“`

  • `source.cab`: The path to the cabinet file you want to extract.
  • `-F:*`: Specifies that all files within the cabinet archive should be extracted.
  • `destination_folder`: The directory where the extracted files will be placed.

For example, to extract all contents of `drivers.cab` to a folder named `C:\ExtractedFiles`, you would use:

“`
expand drivers.cab -F:* C:\ExtractedFiles
“`

If you want to extract specific files, replace the asterisk with the file name:

“`
expand drivers.cab -F:driver.sys C:\ExtractedFiles
“`

Another useful command-line tool is `DISM` (Deployment Image Servicing and Management), which can be used to install cabinet files related to Windows updates and drivers. The command for adding a package using DISM is:

“`
dism /online /add-package /packagepath:[path_to_cab_file]
“`

This command integrates the `.cab` package into the current Windows installation (`/online`).

Using Third-Party Tools to Manage Cabinet Files

While native Windows tools like `expand` and `DISM` are effective, several third-party applications offer enhanced features for handling cabinet files, including better user interfaces, batch processing, and support for multiple archive formats.

Popular third-party tools for `.cab` files include:

  • 7-Zip: A free and open-source archive manager that supports `.cab` files among many other formats. It offers a user-friendly GUI and can extract files via right-click context menus.
  • WinRAR: A commercial archive utility with support for `.cab` files, allowing extraction and browsing of archive contents.
  • Cabinet Viewer: Specialized software focusing exclusively on `.cab` files, useful for detailed inspection of archive contents.

These tools typically allow users to:

  • View the contents of `.cab` files without extracting.
  • Extract single or multiple files selectively.
  • Create `.cab` archives (in some cases).

File Association and Installation Context

Understanding how `.cab` files interact with the operating system is crucial for successful installation. Cabinet files often contain system drivers, software components, or updates that require proper installation mechanisms beyond simple extraction.

For driver installation, the `.cab` file usually includes `.inf` files (setup information files), `.sys` files (system drivers), and related data. After extraction, you need to install the driver via Device Manager or command line tools like `pnputil`.

Common steps include:

  • Extract the `.cab` file to a folder.
  • Open Device Manager.
  • Right-click the device to update.
  • Choose “Update driver” and select the extracted folder.

Alternatively, using `pnputil`:

“`
pnputil /add-driver C:\ExtractedFiles\*.inf /install
“`

This command adds and installs all driver packages found in the specified folder.
