Features
The contents of ZIP, 7Z, RAR, TAR, GZIP, ISO and CAB archives can be inspected, selected files or the entire archive extracted, and new archives created from folders and protected with AES-256. No data is uploaded.
Key features
- Content inspection
- Folder tree and search; size, packed size, ratio and date columns. The details panel shows format, method, encryption and unpacked size.
- Extraction
- All contents or a selection are extracted to a folder, with options for a subfolder named after the archive, preserving the folder structure, and overwriting. Double-clicking a single file prompts for a save location.
- Archive creation
- From files or folders: ZIP, 7Z, TAR, TAR.GZ, TAR.XZ, TAR.BZ2 or GZIP. Store, Fast, Normal and Best levels; estimated size, progress and cancellation.
- Passwords
- ZIP archives are created with AES-256, 7Z archives with AES-256 and encrypted file names. For opening, ZIP (AES and ZipCrypto) and password-protected 7Z and RAR are supported.
- Conversion
- An archive is converted to another format, for example RAR to ZIP or 7Z to TAR.GZ, without a temporary folder.
- Integrity test
- The CRC of every file is verified and any damaged files are listed.
- Format detection
- The format is detected from the content rather than the file name. Archives are opened via the file picker, drag and drop, "Open with", or the recent files list.
- Safe extraction
- Paths are sanitised: ".." and absolute paths cannot write outside the selected folder.
- Streaming
- ZIP reading/writing and single-file GZIP are streamed to disk; in Chrome and Edge, a new archive is written directly to the selected location.
- Background processing
- 7-Zip runs in a separate worker thread; the interface remains responsive and cancellation takes effect immediately.
- Context-dependent dropping
- A dropped archive is opened; any other dropped file starts a new archive.
- Desktop-specific functions
- In the desktop application: extraction next to the archive, "Show in Finder", dragging files from an archive into Finder (up to 512 MB), and a "Compress with Arkelo" Quick Action in Finder.
