## 説明

Over time, your WordPress database accumulates a massive amount of unnecessary data—
like post revisions, auto-drafts, orphaned metadata, and expired transients. This
bloat slows down your site and increases your backup sizes.

**Dejunk DB** is a lightweight, intuitive, and highly secure tool designed to clean
up this orphaned and duplicated data, optimizing your database for peak performance.

Before making any changes, Dejunk DB provides a built-in **Backup Engine** so you
can safely create a snapshot of your database and download it locally.

### 🚀 Key Features

 * **Built-In Database Backups:** Create, download, and manage secure `.sql` backups
   of your database directly from the plugin dashboard before you clean.
 * **Preview Before Dejunking:** View the exact items (up to 500 records) that are
   flagged for deletion in a clean, AJAX-powered modal so you know exactly what 
   is being removed.
 * **Post Data Cleanup:** Safely remove Post Revisions, Auto Drafts, Trashed Posts,
   and Orphaned Post Meta.
 * **Comment Cleanup:** Quickly delete Unapproved Comments.
 * **User & Term Cleanup:** Clear out Orphaned User Meta and Orphaned Term Relationships.
 * **Options Cleanup:** Flush stale and expired Transient Options (`_transient_`
   and `_site_transient_`) that bloat the `wp_options` table.
 * **Table Optimization:** Run standard MySQL `OPTIMIZE TABLE` commands on all your
   WordPress tables with a single click.
 * **Global “Dejunk Everything” Switch:** A master switch to clean up all identified
   junk sections instantly.
 * **Clean Uninstall:** When you uninstall Dejunk DB, it automatically cleans up
   its transients and securely deletes all backup files it created, leaving zero
   footprint.

_Note: Any dejunking done to your database is irreversible. Please always utilize
the built-in backup tool before running a cleanup._

## インストール

 1. Upload the `dejunk-db` folder to the `/wp-content/plugins/` directory, or install
    the plugin directly through the WordPress plugins screen by searching for **Dejunk
    DB**.
 2. Activate the plugin through the ‘Plugins’ menu in WordPress.
 3. Navigate to **Tools -> Dejunk DB** in your WordPress admin menu.
 4. **Important:** Click “Create Backup” in the Database Backups card.
 5. Review the junk categories and click “Clean” individually, or use “Run Global Dejunk”
    to clean everything at once.

## FAQ

### Is it safe to delete post revisions and orphaned meta?

Yes. Orphaned meta refers to data left behind when a post or user is deleted. Revisions
are old versions of your posts. Removing them will not affect your live website 
content, but will significantly reduce database size.

### Where are the database backups stored?

Backups are stored in your `wp-content/uploads/dejunk-db-backups` directory. The
plugin automatically generates an `.htaccess` file and an `index.php` file inside
this folder to block direct web access, keeping your backups secure.

### Can I restore a backup directly from the plugin?

For strict security compliance, automatic SQL restoration is not included in the
plugin. To restore your database, simply download the `.sql` file from the dashboard
and import it using phpMyAdmin, WP-CLI, or your hosting control panel.

### Does Dejunk DB leave files behind if I uninstall it?

No. Dejunk DB hooks into the WordPress uninstall process. If you delete the plugin
from the WordPress admin, it will automatically remove its generated backup folder
and all `.sql` files to ensure no sensitive data is left behind.

### Why can I only view 500 items in the preview modal?

To prevent memory exhaustion and browser crashing on large sites that may have hundreds
of thousands of junk rows, the preview query is intentionally limited to 500 items.
The “Clean” action, however, will remove all of them.
