Frequently Asked Questions
No. Packaged builds bundle the 7z sidecar binary. Install from the downloads page for your OS.
Zinnia uses 7-Zip under the hood, so it supports common formats including 7z, ZIP, TAR, GZIP, and others that 7z handles. Use Power workspace for advanced compression options.
Yes. Zinnia registers archive types on Windows, Linux, and macOS. Use Open with Zinnia or Extract with Zinnia where your platform exposes those actions.
Tagged v* GitHub releases publish updater manifests and signed artifacts. The app can notify you when an update is available.

View LicenseTo mitigate potential security concerns (CVE-2026-58052) while 7-Zip affected-version details are finalized, Zinnia temporarily disables RAR extraction on Windows when using the bundled 7-Zip version 26.02 or older. You can still browse, test, and convert RAR archives on Windows. Extraction remains fully functional on macOS and Linux.
Launch Zinnia once to register the services. If the status in Settings -> OS Integration shows "Not enabled", go to Keyboard Shortcuts -> Services (this is automatically opened when clicking "Enable" in the app settings) and check the boxes for Extract with Zinnia and Compress with Zinnia.
No. Zinnia remains a standard Win32 desktop application. In signed builds, it uses a lightweight sparse identity package (MSIX) solely to register the shell extension DLL (zinnia_shell.dll) with Windows 11. Uninstallation cleanly removes both the app and the MSIX package registration.
Flatpak sandbox configurations do not permit Zinnia to run arbitrary network update scripts or bypass the package manager. The in-app self-updater is completely disabled for Flatpak builds, and updates should be managed through Flathub or your desktop environment's software manager.
