People who cannot open a damaged ZIP archive can use DataNumen Zip Repair to attempt recovery of its contents. The program scans the selected archive and writes recoverable data to a new ZIP file.
Archive repair workflow
Choose the damaged ZIP file and a destination for the repaired archive, then start the repair. DataNumen Zip Repair examines the archive structure and rebuilds data it can recover into a new ZIP file. This gives you a separate output archive to try opening or extracting.
The tool targets common archive problems such as corruption that prevents a ZIP file from opening and CRC errors reported during extraction. Recovery depends on the data that remains intact, so a badly damaged archive may yield only some of its contents.
Batch repair and SFX archives
Batch mode lets you run repairs on multiple ZIP files as a group, which is handy when several archives are affected. DataNumen Zip Repair also handles self-extracting ZIP archives, so those files can be included in the recovery workflow.
- Select archives for repair and use batch processing for a group of files.
- Recoverable contents are written to a repaired ZIP archive.
Recovered contents
The goal is to recover files stored inside a damaged archive, including cases where normal ZIP tools stop because of an error. The program reconstructs whatever data it can read; it cannot guarantee that every file in every archive will be restored.
