🛠️ Repair Capabilities
🔧 Corruption Types We Address
CRC (Cyclic Redundancy Check) Errors ⚠️ The most common archive corruption—data integrity verification failures that prevent extraction. Our techniques bypass or repair CRC-protected blocks.
Header Corruption 📋 Damaged central directory or local headers that make archives appear empty or unreadable. Recovery focuses on header reconstruction.
Incomplete Archives 📊 Partially downloaded or truncated files missing end-of-archive markers. Techniques include extracting available data and recovering from redundancy.
Split Archive Issues 🔗 Missing volumes in multi-part archives or volume sequence corruption preventing reassembly.
Password/Encryption Issues 🔐 Corrupted encryption headers preventing decryption even with correct passwords.
⚡ Advanced Repair Features
- Force Extraction - Extract readable data despite errors
