To access the contents of a .7z file, a file archiver utility is required. Common programs include 7-Zip, which is open-source, or other tools like WinRAR and PeaZip.

Once a compatible program is installed, right-clicking the file usually provides an option to "Extract" or "Unzip" the contents to a folder on the computer.

If the goal is to understand how to manage compressed archives or how to use specific extraction software, more detailed instructions can be provided.
