Designed for large forums

The scalable scan engine supports chunked low-priority background processing to avoid ACP timeouts and reduce load on large forums.

Supports:

local filesystem storage
XenForo filesystem abstraction
Cloudflare R2
S3-compatible storage

Remote-aware scans avoid downloading full attachment objects where possible.

Safe duplicate cleanup

Duplicate cleanup uses a dry-run first workflow and intentionally avoids deleting referenced attachments automatically.

Only duplicate attachment data rows with zero active attachment references are considered safe for automated deletion.

Current status

This addon is currently considered an early access / beta release while additional large-scale testing and edge-case hardening continues.

Recommended before production deployment:

full database backup
filesystem backup
testing on a staging environment first
