Checksum does not match
What to do when a downloaded archive hash differs from the official SHA-256 checksum.
What usually causes this?
Most archive problems come from incomplete downloads, missing split parts, password protection, unsupported compression methods, files renamed with the wrong extension, or a tool that does not support the archive variant.
Safe troubleshooting checklist
- Check the file size and confirm the download completed.
- Make sure all split archive parts are in the same folder.
- Inspect the file locally before uploading it anywhere.
- Use the exact password if the archive is encrypted.
- Try a different trusted local app when the format is uncommon.
Privacy-first recommendation
If the archive contains personal, financial, family, medical, business, or client documents, avoid upload-based extractors. Use browser-local or desktop-local tools instead.
