Quick Slugs

TIEro

A simple plugin to find files which are stored in the WP uploads folder (and sub-folders) but which have no corresponding entry in the Media Library.
The plugin creates a new unattached media record for each file, plus metadata where appropriate. You can then delete leftover files through the normal WordPress Media Library UI.

TIEmediahelper Media Library Tools

Find leftover files stored in the WP uploads directory tree which are missing from the Media Library.
