: Locate the file in your folders, right-click it, and select 7-Zip > Extract here (or "Extract to..." to pick a specific folder).
: Open the 7-Zip File Manager, find your archive, and drag the video file inside to your desktop.
: Ensure you trust the source of the file before extracting it.
: Once extracted, you should see a video file (likely an .mp4 or .mkv). You can then play it using standard media players like VLC Media Player or Windows Media Player. Important Notes
: The .7z format is often used to make large video files easier to send or store.
You can use 7-Zip on any computer, including a computer in a commercial organization. You don't need to register or pay for 7-Zip.
