How to use 7-Zip?

As for using 7-Zip, the program offers two primary methods to work with compressed files. The first is through its file manager interface, where users can directly open the application and interact with files and archives, much like they would in any file explorer. This is a comprehensive way to manage compression and extraction but may seem daunting for those new to such applications.

Alternatively, 7-Zip integrates with the Windows Shell, allowing users to quickly access its features by right-clicking files or folders in Windows Explorer. This “context menu” approach is particularly user-friendly, streamlining the process of adding files to archives or extracting them without having to navigate through the full program. It simplifies the process by providing quick-access options like “Add to archive…” or “Extract here…” making it highly efficient for routine tasks.

This integration also extends to email, enabling users to compress and attach files directly to emails for easy sharing. The user interface can be switched between dual and single-pane views, accommodating users’ preferences and facilitating drag-and-drop actions, further enhancing the software’s convenience and usability.

Why do people still use 7-Zip?

People still choose 7-Zip for its no-cost, high-efficiency archiving and strong encryption features, even with several alternatives available. While WinRAR is highly popular, especially for its proprietary RAR format, and WinZip is well-known but requires a purchase, 7-Zip remains a go-to for its zero-cost, open-source flexibility, and support for numerous file formats.
