Will the legacy system folder structure be preserved during extraction?

Yes. Deliteful preserves the complete internal directory hierarchy. The source system taxonomy encoded in subdirectory names and nesting is maintained exactly, reducing remapping work before ingestion.

How does Deliteful handle corrupted entries in legacy ZIP exports?

Corrupted files are detected and skipped automatically. The remainder of the archive and batch continues to process. You receive the successfully extracted files without having to manually identify and remove problem entries.

Can I extract ZIPs from multiple legacy source systems in one batch?

Yes. Batches support up to 50 files or 2 GB total. Each ZIP is extracted into its own isolated directory, preventing filename collisions between different source systems exporting identically named files.

What is the extraction size cap per task?

Total extracted output is capped at 5 GB per task. For very large legacy exports, split into multiple batches. The cap prevents runaway decompression from oversized or malformed archives.

Extract ZIP-Packaged Legacy Exports for Data Migration

Data migration projects frequently begin with a set of ZIP-packaged exports from legacy systems — database dumps, flat file exports, or document stores — where the archive folder structure maps directly to the source system taxonomy. Losing that structure during extraction forces costly remapping before ingestion can begin. Deliteful extracts these archives with every subdirectory intact and handles corrupted files without stopping the batch.

Legacy system exports are notoriously inconsistent in quality. A ZIP export from a decade-old document management system may include partially written files or entries with non-standard path formats. Standard desktop extraction tools will often abort on the first malformed entry, leaving you with an incomplete file set and no clear indication of what extracted successfully. Deliteful skips corrupted entries and continues, returning a complete log of what was and was not extracted.

For migrations involving multiple source systems, batch processing matters. Deliteful handles up to 50 ZIP files or 2 GB per batch, with each archive extracted into its own isolated directory to prevent filename collisions between source systems. The 5 GB per-task extraction cap accommodates most departmental export packages while protecting against oversized or malformed archives.

How it works

1
Upload legacy system ZIP exports
Batch upload up to 50 ZIP exports or 2 GB from legacy system migrations.
2
Integrity check and corruption skipping
Deliteful validates each archive and skips corrupted entries without halting the batch.
3
Download with source structure preserved
Receive extracted files with the original folder hierarchy intact, ready for migration mapping.
