## Key features

- **Scanning:** Scans multiple folders, drives, network shares or MTP devices in one pass. Running elevated speeds up scans of local NTFS drives.
- **Disk usage views:** Shows the largest files and file types alongside treemaps, sunbursts and flame graphs, and compares logical with physical sizes.
- **Search and duplicates:** Searches by name, size, type or owner. Duplicates are found by comparing content hashes, with optional sparse hashing for probable matches.
- **Reports and monitoring:** Scan snapshots can be saved and reopened, reports exported as CSV or JSON, scans automated, and file-system changes watched.
- **Cleanup and recovery:** Runs cleanup tools on selected items and can attempt to recover deleted files from local NTFS, exFAT and FAT drives.
- **Permissions and storage analytics:** Inspects permission entries and estimates storage tier costs from file sizes and modification ages.
