OctoSize Media Scanner

OctoSize Media Scanner helps site owners find oversized images, large uploads, and other heavy media library files quickly.

Features:

• Adds Media > OctoSize Media Scanner in wp-admin
• Scans attachment file sizes from the uploads directory
• Sorts largest files first by default
• Supports sorting by size, title, type, or path
• Filters by minimum size in 5 MB increments
• Searches by filename, title, or MIME type
• Supports optional nightly WP-Cron scans
• Uses caching and a scan lock to reduce repeated heavy work

Performance notes:

• Attachment scanning runs in batches
• Results are cached to avoid repeated full scans
• Cache is invalidated when attachments are added, edited, or deleted

Security notes:

• The admin page is restricted to users with the upload_files capability
• Manual actions are protected with nonces
• Input is sanitized and output is escaped
• File reads are restricted to uploads-based attachment paths
