Delve resources
Choose a Mac disk analyzer by workflow: compare prices, treemap and sunburst views, cloud access, and the tradeoffs of four focused tools.
A disk map helps you spot large clusters. A sorted list helps you follow names and paths. Before choosing, decide whether you need to inspect files on your Mac or an entire connected cloud account. Those are different jobs.
On a small screen, scroll the table sideways to see every feature.

| OmniDiskSweeper | Free download | Size-sorted file list | Drive and folder inspection |

Consider Delve if you want rectangles for comparing file sizes and rings for following folder depth in the same app. Review candidates in its Collector before moving them to Trash. Check your Mac first: Delve requires Apple Silicon and macOS 12 or later, and does not connect directly to cloud accounts.
Compare Delve with DaisyDisk →Choose DaisyDisk when remote account storage is part of the problem, or when you prefer a sunburst. Its support for Intel Macs and macOS 10.13 onward also makes it an option outside Delve’s requirements. A local sync folder alone does not show everything held in a remote account.
Compare DaisyDisk with GrandPerspective →Start here if you want a rectangular disk map without a purchase. Its filters and color choices suit repeated investigations of particular file types or folders. Choose it for that configurable view; if you want to switch between rectangles and rings, compare it with Delve.
Compare Delve with GrandPerspective →Pick a size-sorted list when filenames and folder paths help you decide what to inspect next. OmniDiskSweeper offers a direct way to open or trash files. If spatial patterns are easier for you to read, a treemap may be a better starting point.
Compare GrandPerspective with OmniDiskSweeper →Use the same folder in each candidate. Can you find the largest item, understand its path, and inspect it before removal? A useful view should make your next decision clearer. Check system requirements and removal behavior before committing to an app. For broader coverage, read the Mac disk analyzer buyer’s guide.
