Repair a corrupted ZIP archive (.zip)
A ZIP archive stores each file with its own small header, then a central directory (the index) at the very end. If the end of the file is missing, tools say the archive is invalid — but every file before the cut can still be read.
What our repair does
- Find every file by scanning for its header, even without an index
- Recover partly written files up to the damage
- Check every file's checksum (CRC)
- Write a clean new archive
The check and preview are free. The repaired file costs $4.99.
