DiskWise – Disk Analyzer

DiskWise – Disk Analyzer shows you exactly where your disk space is going. It scans your WordPress installation and lists the size of every folder and file, so you can quickly find what is taking up room.

Features:

• See the size of each folder and file, sorted largest first.
• Click any folder to drill down into it.
• A “% of folder” bar to spot the biggest items at a glance.
• Progressive scanning — folder sizes are computed in the background so the page stays responsive.
• Results are cached for one hour; one click clears the cache and rescans.
• Shows total disk free and disk total.

The screen lives under the Tools menu. Only administrators (manage_options) can use it.
