Disk Space Analyzer
Disk Space Analyzer is a macOS utility that scans storage, shows what uses disk space, and helps you find large files and folders.
What is Disk Space Analyzer?
Disk Space Analyzer is a Mac disk usage utility for exploring storage and finding files and folders that take up significant space. It helps users understand how a Mac’s internal drive, external disks, network storage, and selected folders are organized by size. The app presents scanned data visually and lets you drill down through folders to inspect their contents in more detail. It also supports common file-management tasks such as previewing items, checking file information, and moving, copying, or sending unneeded files to the Trash. This makes it useful for people who want to free up storage, review bulky project folders, or track down old content that is no longer needed. Disk Space Analyzer is published by Nektony LLC for macOS.

Safety overview
Status: Mostly safe
This app’s behavior is consistent with a disk analysis utility: it scans storage locations and may request Full Disk Access on macOS so it can inspect files across the drive. That permission is sensitive because it allows broad visibility into your files, so grant it only if you want full-drive analysis and you trust the installed copy. The bundle ID com.nektony.Disk-Expert-SIII differs from the product page branding "Disk Space Analyzer," so check that the app is signed by Nektony LLC in Finder or System Settings before giving it expanded access.
Recommendation: Keep it if you use it to understand storage usage, locate large files, or clean up crowded disks. If you do not use disk analysis tools, you can remove it without affecting macOS itself; the main impact is that you will lose its storage-visualization and file-review features until you reinstall it.
