Add-ons Attachment Integrity 5.7.4

Frequently Asked Questions​

Does this support XenForo 2.3?​

Yes. The addon is built for XenForo 2.3.

---

Does this work with Cloudflare R2 or external storage?​

Yes.


The addon includes external storage aware scanning and works with:

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

Where possible, remote-aware scans avoid downloading full attachment objects.

---

Will this work on very large forums?​

Yes.


The addon includes scalable low-priority background scanning designed for forums with very large attachment libraries.


Features include:

• chunked scan processing
• resumable scans
• configurable batch sizes
• low-priority processing
• background queue support

---

Does this delete attachments automatically?​

No — not blindly.


The addon is intentionally designed to avoid unsafe automatic deletion behaviour.


Duplicate cleanup uses:

• queue-based processing
• dry-run validation
• reference safety checks

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

---

What scan modes are available?​

Existence only​

Fastest mode. Checks if attachment objects/files exist.

Metadata mode​

Checks:

• existence
• file size
• readability

Recommended for most forums.

Deep verification​

More intensive validation intended for corruption/migration investigations.

---

Can scans run in the background?​

Yes.


Large scans use XenForo’s job system and can run as low-priority background jobs.

---

Can scans be resumed?​

Yes.


Scalable scans store scan state and can resume from the last processed attachment data ID.

---

Does the addon support exports?​

Yes.


Supported export/report formats include:

• CSV
• JSON
• TSV
• HTML

---

Does the addon include repair tools?​

Yes.


The addon includes:

• repair queue system
• thumbnail verification
• duplicate analysis
• attachment integrity reporting
• audit logging

---

Is this safe to use on a live forum?​

The addon is designed with safety in mind, but as with any maintenance or cleanup tool:

• always back up your database
• always back up attachment storage
• test on staging first where possible

This is especially important for very large forums or external storage environments.

---

Does this support CLI/large-server workflows?​

Yes.


CLI support and scalable background processing are included for large attachment libraries and long-running scans.

---

Will this rebuild or rewrite post attachments automatically?​

No.


The addon intentionally avoids dangerous automatic attachment rewrites/repointing to reduce the risk of post corruption.
