Thumbnail Manager / Media Management August 3, 2026

Scan, Review, and Approve a Prune Manifest

Remove old generated thumbnails through the five-step immutable manifest workflow.

Applies to 1.4.0+ Free Stable Verified July 29, 2026

Scanning only builds a hashed manifest. Deletion starts only after an administrator reviews and explicitly approves that exact manifest.

Open the feature

Go to Tools > Thumbnails > Prune Files.

Before you start

  • Create a verified uploads backup.
  • Choose the registered sizes that must remain.
  1. Select all uploads or explicit year/month folders.
  2. Choose Scan and review.
  3. Filter and paginate the manifest; review paths and estimated storage.
  4. Confirm the reviewed manifest.
  5. Run resumable deletion and inspect errors.

What success looks like

  • Only approved generated files are removed.
  • Attachment metadata is updated and original uploads remain.

Important notes

  • Unmapped disk-only filename matches are reported and skipped by default.
