An open-source, cross-platform file archiver that provides a graphical interface for various compression algorithms.
The details
The software manages file extraction through an updated UNPEA procedure, which now directs output to a randomly named temporary work folder. This technique isolates extracted contents to prevent potential file system collisions during heavy operations. Users can now access the 'Open with' screen using the new Shift+F12 keyboard shortcut.
