TreeSize for Mac
A folder-size browser and a storage-reporting tool solve different problems. The right Mac alternative depends on which part of TreeSize you use.
Khaos Studios makes Delve. This comparison draws on the official product documentation linked below.
JAM Software’s support documentation says its TreeSize product runs on Windows and has no Mac edition. If you see another Mac app with a similar name, check the developer rather than assuming it is a port of JAM Software’s product.
For finding large folders on your Mac, there are several native options. For scheduled reporting and file-server management, check those requirements separately before choosing a replacement.
| Your requirement | An option to evaluate | What to check |
|---|---|---|
| Browse folder sizes | OmniDiskSweeper | Whether a sorted list covers the investigation |
| Free visual analysis | GrandPerspective | Filters, saved scans, and image or text exports |
| Visual exploration and cleanup | Delve | Treemap, sunburst, previews, and Collector workflow |
| Familiar Windows-style analysis | WizTreeMac | Mac feature differences, exports, and commercial licensing |
| Scheduled enterprise reporting | Evaluate requirements individually | Scheduling, permissions, report formats, and support for your storage |
Delve is a focused disk visualizer. It is not a replacement for every TreeSize Professional reporting or administration feature.
If the goal is to find what has grown, start with a folder-size list or visual map. A list keeps the names and hierarchy prominent. A treemap helps you compare the relative size of files. A sunburst shows the nested structure as rings.
Delve combines both visual layouts with Quick Look and a Collector for selected files. After a 14-day free trial, support our work for $4.99 once or get Delve free through referrals. It runs on macOS 26 or later with Apple Silicon. GrandPerspective and OmniDiskSweeper offer free starting points.
Write down the output you need before switching: a one-off file list, a repeatable report, a scheduled scan, or a historical view. A disk map alone does not meet all of those requirements. JAM Software documents scheduling and reporting in TreeSize Professional.
If you are considering WizTreeMac for exported file data, review its platform differences and license terms. Test the required format and scan location as part of the evaluation.
For “which folder is using my disk?”, evaluate OmniDiskSweeper, GrandPerspective, or Delve according to your preferred view. For recurring reports or server administration, choose only after confirming the full workflow.
JAM Software says TreeSize is a Windows product and does not have a native Mac edition. Check the developer of similarly named apps.
OmniDiskSweeper offers a free size-sorted view of files and folders. GrandPerspective provides a free treemap through its official SourceForge download.
Delve can help with visual disk analysis and selected-file cleanup. It does not replace the full scope of TreeSize Professional’s reporting, scheduling, or server-administration workflows.
Finder can help inspect sizes within familiar folders. A dedicated disk analyzer provides a broader overview when you need to find large items across many directories.
