What Space Gremlin is
Space Gremlin is a paid macOS utility for locating large files and folders that consume drive space. It visualizes disk usage with squarified treemaps, helping users inspect connected drives, external drives, or selected folders. Shortcuts open predefined home-directory locations, while the tree view supports zooming, rescanning, and ignoring items that add clutter. Tooltips show file or folder size and location, and Quick Look previews selected items. After finding space-consuming data, users can compress files or folders or move them to the Trash. Pro mode adds quick scans of connected drives, more predefined user folders, and Admin mode for restricted files. The Space Gremlin plan costs $4.99 a month and includes a free trial; no free plan is available. The app moves items to Trash rather than permanently deleting them, and file-system metadata is not reported in any scanning mode. A Pro demo scans limited folders but cannot scan user-selected drives and folders.
