Clean up unused images and other files from your uploads folder.
This plugin inspects every file within the uploads folder. For each file, it searches pages or posts that
reference the file. That is, the plugin searches for the part of each file's path that comes after the path
to the uploads folder, such as
2010/01/my great but forgotten image.jpg.
The path is searched as-is, as well as URL-encoded with '%20' for spaces, and the same with '+' for spaces -
2010/01/my+great+but+forgotten+image.jpg. HTML entity-encoded
forms of all of these are also searched.
If no matches are found, then the file is considered unused.
Note that this plugin plays it safe, and does not distinguish between older post/page revisions and the current version of a post/page. If a revision references a file, the file will be considered still in use.
If something goes wrong, you can always restore. If you have shell access to your site, this is easy. Simply log in,
navigate to your
wp-content/plugins directory, and locate the Upload Janitor archive - it will look like
upload_janitor_archive_YYYY-mm-dd.tar.gz. Then, type:
tar zxf <archive name> .
This will restore all files within the archive.
If you do not have shell access to your server, you will have to download the archive, extract it, then upload the contents back to your server. The archive will be accessible at http://your-blog.com/wp-content/uploads/upload_janitor_archive_YYYY-mm-dd.tar.gz
