Will the folder classification hierarchy inside document archive ZIPs be preserved?

Yes. Deliteful preserves the complete internal directory structure on extraction. Nested subdirectories reflecting records taxonomies are maintained exactly as they appear inside the archive.

What happens if some archives in a migration batch are corrupted?

Corrupted archives are detected and skipped automatically. The remaining archives in the batch continue processing normally, so partial corruption does not abort the full migration extraction.

Can I process a large set of legacy document ZIPs at once?

Yes. Batches support up to 50 files or 2 GB total, and each ZIP is extracted into its own isolated directory. For large migrations, split into multiple batches if needed.

Is there a risk of files being extracted to unexpected locations?

No. Path traversal attacks — where file paths inside a ZIP reference '../' directories — are blocked before extraction. All files are written only to their designated isolated extraction directory.

Unzip Document Archive Batches for Records Management

Records management teams migrating legacy document stores or receiving historical file transfers often encounter ZIP-packaged batches where the folder structure encodes the classification hierarchy — department, year, record type. Losing that structure on extraction means reclassifying thousands of documents manually. Deliteful extracts these archives with every subdirectory intact and skips corrupted files without stopping the batch.

Document archives transferred between systems are frequently packaged as ZIP files with deeply nested directories reflecting the source records management taxonomy: 'Legal/Contracts/2019/Vendor/'. If extraction flattens this structure, the entire classification context is lost and must be reconstructed from file metadata — an expensive manual process for large transfers. Deliteful preserves the complete internal hierarchy on every extraction.

Bulk archive migrations amplify the corruption risk: a single corrupted ZIP in a set of 30 can halt an entire extraction batch using standard desktop tools. Deliteful detects and skips corrupted archives automatically, allowing the remaining batch to complete. The 5 GB extraction cap per task handles most departmental archive packages, and batches of up to 50 files can be processed together.

How it works

1
Upload archive batch
Upload up to 50 document archive ZIPs or 2 GB per batch for bulk extraction.
2
Corruption detection and skipping
Deliteful verifies each archive and skips corrupted files, letting the rest of the batch complete.
3
Download with taxonomy hierarchy intact
Extracted documents are returned with the original folder classification structure preserved.
