Sandboxie is a software application designed to enhance the security of your computer by running programs and accessing the internet within an isolated environment, often referred to as a "sandbox." This isolation helps to prevent any malicious software or harmful activities from affecting the main system. By using Sandboxie, activities and programs are confined to the sandbox, ensuring that any changes, downloads, infections, or breaches remain segregated and can be easily deleted without impacting the overall integrity or security of your primary system. Sandboxie is suited for browsing, testing applications, and opening files that might pose a risk if accessed directly.
