Common errors

Repair a corrupted zip

Recover files from a corrupted zip on your own computer, without uploading anything. Free diagnosis and preview before you pay.

How the problem shows up

• CRC error when extracting
• "Unexpected end of archive"
• The zip has the right size but won't open

Why it happens

Parts of a zip can be damaged by disk failures, incomplete transfers or programs that wrote over the file.

What to do now

1. Keep the original zip untouched.
2. Open Neural Repair and drag the file in.
3. See in the preview which files come back whole and which come back partially, and only save if it's worth it.

No program fixes 100% of cases. Zeroed files or files encrypted by ransomware have no content to recover, and the diagnosis tells you so before you pay anything.
