A more transparent cleanup workflow

See what is using space. Review it. Then decide.

JJ Storage Cleaner avoids aggressive automatic-cleanup rules. You choose the folder to analyze, review the results and decide what should happen.

Scans are designed to be read-only. Protected macOS and application locations are excluded, and supported removals move selected files to Trash instead of permanently deleting them.

Core tools

Three ways to understand where your storage is going.

Each tool is built around review and context, so you can inspect what was found before taking action.

01

Large Files

Find the files that are taking up the most space.

Browse and filter large files inside folders you select. File size, path and Finder access stay visible so you can understand each item before making a decision.

  • Filter by minimum file size
  • Review paths and file sizes
  • Reveal any result in Finder
  • Select only the files you want to review for removal

02

Duplicates

Identify duplicate content, not just matching names.

JJ Storage Cleaner verifies duplicate file contents and groups identical copies for review. Different filenames can still be recognized when their contents are the same.

  • Content-verified duplicate groups
  • Estimated storage savings
  • Review every copy and its location
  • Designed to keep at least one copy in each group

03

Developer Files

Review build outputs and generated development data.

Developer Files helps surface build outputs, dependency folders and generated data that may be consuming storage. This area is intentionally review-only so nothing is removed automatically.

  • Detect development-related folders
  • See estimated disk usage and file counts
  • Reveal detected folders in Finder
  • No automatic deletion from Developer Files

Safety first

Cleanup should feel deliberate, not risky.

JJ Storage Cleaner uses a conservative approach: analysis first, review second, action last.

Privacy by design

Your files are analyzed locally.

The app does not upload file contents, filenames, folder paths, duplicate hashes or scan results to JJ Studio Entertainment servers.

JJ Storage Cleaner does not use third-party advertising or cross-app tracking, and its Mac App Store privacy disclosure is “Data Not Collected.”
