A lightweight, hyper-focused Windows desktop utility designed to bulk-archive folders into secure, split, encrypted RAR volumes with built-in native integrity testing and automated checksum tracking.
Developed by Natasun.
When managing massive directories or preparing data packages for platforms with rigid file size restrictions (like Telegram, older cloud drives, or email attachments), splitting folders manually is incredibly tedious.
This utility automates the entire process cleanly through a native UI, acting as a robust visual wrapper for the high-performance rar.exe engine.
- Bulk Processing: Point the tool at a root directory, and it loads all sub-folders automatically. Check or uncheck exactly what you want to process.
- Auto-Resilient Architecture: Includes an asynchronous task engine. If a task fails or you hit STOP, it automatically halts operations and executes a strict system wipe to delete half-baked, corrupted, or locked
.rar/.partfiles from your destination drive. - On-the-Fly Custom Splitting: Select industry standard pre-sets or manually type custom parameters directly into the configuration input box (e.g.,
1900mfor Telegram limit,500m,4g). - Header Encryption: Applies full
-hpformatting to ensure file names inside archives are hidden from view without entering the password. - Native SHA-256 Logs: Natively compiles standalone
.txtvalidation checksum arrays directly in the output directory—no external Windows binaries (certutil) required.
