Sandbox lets you run applications in a safe virtual environment, isolated from the rest of your device’s system. This feature is useful when you want to run suspicious or untrusted applications without risk. Sandbox storage is a file space completely isolated from the rest of your system and other Sandboxes.

When you run an application in Sandbox, all necessary files are always copied to Sandbox storage where they can be modified as needed without affecting the original files. Any new files created during virtualization are also saved to Sandbox storage.

By default, Sandbox storage is created in the same drive as the original file. If there is insufficient space on the pre-selected drive or you encounter disk performance issues, you may need to select a different drive or browse for another location.

Sandbox is not available for macOS devices.
