What can you learn from a ZIP?
ZIP is the most widely used archive format, and it's also the foundation for formats like JAR (Java apps) and APK (Android apps). Inside every archive is a directory listing every file, its size, how it was compressed, and when it was last modified.
FileAtlas reads that directory and builds a browsable file tree so you can see exactly what's in an archive without extracting it. Perfect for checking downloads before opening them, inspecting app packages, or understanding how files are organized inside a bundle.
