FÆrchiver

A Comprehensive File Archiver That Operates Entirely Offline

FÆrchiver establishes itself as a definitive, no-nonsense utility for Android, providing granular control over compressed files and app backups without ever requiring an internet connection. This application distinguishes itself through a starkly functional interface and a privacy-first architecture, deliberately engineered to operate in complete isolation from the web. Its core competency lies in handling a vast spectrum of archive formats—both common and obscure—while integrating directly with the system for managing APK and data backups. The absence of network permissions is not a limitation but a foundational feature, ensuring all file operations remain strictly local and private.

The tool’s functionality is segmented into creation, extraction, and management workflows. For creation, it supports formats like 7z, zip, bzip2, gzip, XZ, lz4, tar, and zstd, allowing for password protection and multi-volume archive splitting. The extraction engine is notably more extensive, capable of unpacking over thirty different formats including rar5, various disk images (.iso, .dmg, .img), software packages (.deb, .rpm), and legacy types like arj and lzh. A dedicated archive browser lets you inspect contents before extraction, and the editor function permits direct modification of zip, 7z, tar, and even APK/MTZ files by adding or removing internal components. For Android users, the ability to directly install APK files and deploy OBB data folders from within a backup archive streamlines the restoration process significantly.

Beyond basic compression, FÆrchiver implements several technical optimizations. It utilizes multi-threading to accelerate operations on modern multi-core processors and maintains full UTF-8/UTF-16 support for international filenames. On devices running Android 9 and above, it can implement a direct-open method for files under 10MB, accessing content without a full extraction cycle. The application also handles complex scenarios like opening archives directly from email clients, partially extracting specific files, and reassembling split archives (e.g., .001, .z01, .part1.rar sequences).

Core Feature Set

• Broad Format Compatibility: Creates 7z, zip, and tar archives; extracts a vast range including RAR5, ISO, DMG, and executable packages with consistent reliability.
• Direct App Backup Management: Installs APK files and deploys OBB data folders directly from compressed backups, facilitating efficient app restoration.
• Advanced Archive Editing: Enables direct modification of supported archives by adding, removing, or viewing files internally without full decompression.

We suggest trying FÆrchiver if you require a powerful, private, and ad-free tool for detailed archive management and app backup handling on your Android device.
